Type designation

This is the unique reference number (shown above and in
the first column, below) that clearly identifies your drive by 
power rating and frame size. Once the drive’s type designation 
has been selected, the frame size (column 7) can be used to 
determine the drive dimensions, shown on the next page. 

Voltages

ACS250 is available in two voltage ranges:
1   =  110 to 120 V 
2   =  200 to 240 V 
4   =  380 to 480 V
6   =  500 to 600 V 

Insert either “1”, “2”, “4” or “6”, depending on your chosen 
voltage, into the type designation shown above. 

Construction

“01U” within the type designation (shown above) varies
depending on the drive phase and EMC filtering. Choose below
the one you need.

Cooling

Cooling air fl ow for IP20 drives

IP20 drives are designed to be installed in a protective enclo-
sure.  Heat dissipation and air flow values are given to assist 
with sizing enclosure sizes and cooling provisions.  ACS250 
drives 1 HP and above are fitted with heat sink cooling fans as 
standard.  Drives below 1 HP do not have an internal cooling 
fan and rely on natural convection to cool the internal compo-

nents.  The cooling air must be free from corrosive substances 
and must not be above the maximum ambient temperature of 40 
°C (50 °C with derating on IP20 drives only). For more specific 
limits see the individual Data Sheet pages (for IP20 & IP66 drives) 
in this catalog.

Notes:

 

      

1) Dimension Z assumes that the drives are mounted side by side with no clearance. For the IP66 drives, can be installed side-by-side 

with the heatsink fl anges touching.  This gives adequate ventilation space between drives. 

 

 

 

2) Drive must be installed on a vertical fl at surface that is able to support the weight of the drive.   

 

 

 

3) Spacing requirements are guidelines only and do not take into account other sources of heat in the environment.  Operating ambient 
temperature of the drive must be maintained at all times.

Fuses and cable sizes

The following table provides the output current rating informa-
tion for the various ACS250 models. ABB Drives always recom-
mend that selection of the correct ACS250 is based upon the 
motor full load current at the incoming supply voltage.

Cable dimensioning for nominal rated currents is shown in the 
table below together with the corresponding fuse types for 
short-circuit protection of the input power cable.

The rated fuse currents given in the table are the maximums 
for the mentioned fuse types. If smaller fuse ratings are used, 
check that the fuse rms current rating is larger than the nominal 
input current.

If 150% output power is needed, multiply nominal input current 
by 1.5. 

Check that the operating time of the fuse is below 0.5 sec-
onds. The operating time depends on the fuse type, the supply 
network impedance as well as the cross-sectional area, mate-
rial and length of the supply cable. In case the 0.5 seconds 
operating time is exceeded with the gG or T fuses, ultra rapid 
(aR) fuses in most cases reduce the operating time to an ac-
ceptable level.

Notes: 

         

1) Larger fuses must not be used when the input power cable is selected according to this table.   

 

 

 

 

 

 

2) For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses   

 

 

 

3) Other fuse types can be used if they meet the ratings and the melting curve of the fuse does not exceed the melting curve of the fuse mentioned in this table.   

 

4) The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum cable length limit may be increased by 50%. 
When using the ABB Drives recommended output choke, the maximum cable length may be increased by 100% 

 

 

 

 

 

5)The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the motor terminals, depending on the motor cable 
length and inductance. The rise time and peak voltage can affect the service life of the motor. ABB Drives recommend using an output choke for motor cable lengths of 50m or more 
to ensure good motor service life

Type CR Case resistor 

Information and dimensions

Overview

Powerohm’s Type CR resistors are manufactured with quality components for superior performance and increased life expectancy. 
Our case resistors feature a nickel-chromium wire helically wound, then placed inside a ceramic fixture and inserted into a corro-
sion resistant aluminum case. Each coil end is terminated to high temperature wire leads and encapsulated with a ceramic potting 
material. The result is a resistor element electrically isolated, but thermally bound to the outer case to allow the element heat to 
transfer to the metallic case and efficiently cool. The units are supplied with 18” wire leads, and the case is machined to include 
two mounting holes for easy installation.

Type GCE resistor 

Information and dimensions

Overview

The type GCE enclosures are heavy gage screened enclosures featuring a solid bottom and a built-in wiring compartment sepa-
rated from the resistor assembly. The resistors are factory wired to a terminal block mounted in this compartment using high 
temperature Teflon or silicone wire. The terminal compartment also houses a normally closed thermal switch used for detecting re-
sistor temperature overloads. During installation, standard 90ºC rated wire is routed into the compartment through the removable 
1/2 inch conduit knockouts and connected to the factory wired terminal block. 

Our standard unit includes a screened cover which is CNC punched to obtain maximum cooling and professional aesthetics. 
Mounting holes are located inside the enclosure and can be easily accessed by removing the cover. Resistor coils are inter-
connected using stainless steel bus bars, producing a corrosion resistant current path to withstand nearly any harsh industrial 
environment. The standard finish is galvanized, but an optional powder coated, aluminum or stainless steel finish is available upon 
request. As shown in the table below, the size of the enclosure will vary depending on the number of resistor coils required for 
your application. Units are available with louvered covers; add “-W” to the part number and note that the ‘A’ and ‘B’ dimensions 
will increase by an inch. Please do not hesitate to call the factory if you need assistance.

Installation instructions for Powerohm Brake Resistors

CONSTRUCTION: Powerohm braking resistors consists of smoothwound, wirewound or edgewound type resistor coils mounted 
in ventilated enclosures. All current carrying components used to manufacture our resistor coils including the elements and termi-
nals are stainless steel for maximum corrosion resistance. Standard enclosures will be mill galvanized with terminals factory wired 
to a terminal block and normally closed thermal switch. Braking resistors are available with a variety of options such as special 
enclosure finishes and outdoor ratings. 

INSPECTION: Upon receipt of your Powerohm Braking Resistor, be sure to inspect the unit carefully for any shipping damage. 
After unpacking, check the unit for loose, broken, bent or otherwise damaged parts due to shipping. Report any shipping damage 
immediately to the freight carrier. Be sure to verify that the part number and ratings listed on the nameplate conform to the order 
specification. The ohm rating listed on the nameplate is critical (too low of an ohm value may cause damage to the drive).
 
INSTALLATION: 
IMPORTANT: The National Electric Code (NEC) and local regulations govern the installation and wiring of electrical equipment 
such as braking resistors. DC power wiring, AC power wiring, control wiring and conduit must be installed in accordance with 
these codes. 

Powerohm braking assemblies cool by natural convection causing hot air to rise vertically from the enclosure. Braking resistors 
should be mounted in a well ventilated location free of any combustible materials or equipment affected by heat. Units should 
be installed with at least 24 inches of free space above the enclosure top and 6 inches of free space surrounding the enclosure 
sides. If necessary, units can be mounted on spacers or channels to limit heat from conducting from the resistor enclosure to its 
mounting surface. 

Braking resistor enclosures 28 inches or less in width, can be mounted vertically or horizontally. If the unit is mounted vertically, 
it is important that the resistor coils remain in a horizontal position. Also, if a thermal switch is included with the unit, position the 
equipment so the switch remains near the top of the enclosure. See below for vertical mounting details. 

Smaller 28 inch wide enclosures have convenient conduit 
knockouts for easy connection. Remove the proper knockout 
after determining a suitable entry point. Larger units may require 
field punching for conduit entry. It is preferable to route con-
duit near the bottom of the resistor enclosure. After attaching 
conduit, pull wiring into the enclosure for connection to resistor. 
If connecting directly to the terminals on the resistor elements, it 
is necessary to use high temperature silicon or Teflon wire rated 
200ºC. Try to route wiring along the bottom of the enclosure 
and avoid running the wiring across the top or near the resistor 
elements. Units are supplied with either #10, 3/8 or 1/2 inch 
terminal hardware. If you choose to use the factory installed 
terminal block, then you may connect to if using standard 90ºC 
rated wire. Be sure to properly ground the resistor enclosure to 
prevent electrical shock.
A normally closed thermal switch is included with the unit, featuring ¼ inch quick connect terminals. 
 
After installing and wiring to your Powerohm Braking Resistor, return the ventilated cover to its proper position. Securely tighten cover 
hardware (do not exceed 20 inch-pounds of torque). 
 
MAINTENANCE: Periodically check the unit for loose connections and an accumulation of dust or dirt on the inside and outside of the re-
sistor enclosure. Be sure to allow the unit to cool before servicing (contact may result in burn injury). Remove all power before servicing unit 
to avoid electrical shock. Allow at least one minute after input power has been removed for the bus voltage to discharge. Electric shock 
can cause injury or death.Resistor elements should not glow red under normal operating conditions. If the resistor elements glow red you 
may need a higher ratedbraking resistor. 
 
TECHNICAL SUPPORT: If you have any questions about your braking resistor, contact Powerohm for assistance at (800) 838-4694.

Input reactors

Applications:  

Line side power conditioning for AC motor controls to prevent unwanted harmonics and nuisance drive trips as well as to 
prevent excess current during line disturbances that can damage power semi-conductors. There should be a minimum imped-
ance associated with the drive using either AC or DC magnetics.  In many applications, this impedance can come from a supply 
transformer, or if long enough, the supply cable themselves. In most cases, however, the use of an additional input reactor is 
recommended.  
If any of the following conditions exist use of at least a 3% line reactor is recommended:

 

−

Installation has voltage spikes in excess of 6000V peak or lightning strikes.

 

−

Installation has switched power factor correction capacitors.

 

−

Installation has power interruptions or voltage sags in excess of 200Vac.

 

−

When the distribution system kVA is more than 10 times larger than the drive kVA . 

Features:

  

Open, UL Type 1 and UL Type 3R construction with connection terminals. 3%  and 5% 
impedance rating at rated current.

dv/dt output filters 

Applications:  
V1k Output Filters provide motor protection by limiting voltage spikes to 1,000 volts, or below, for long motor cable applications. 
Greatly extends the life of the motor and cable for all applications up to 1000 feet. 
For multi-motor applications note that motor lead length is cumulative and the 1000 foot limit still applies. 
30% reduction in common mode current enough, 

Features:

  

UL Open, UL Type 1 and UL Type 3R construction with connection terminals. 

Note:

 

The drives internal EMC filter must remain disconnected when using these filters.

 

When applying these output filters the drive output frequency is limited to 60Hz.

ABB drive life cycle management model

Spare part, maintenance and repair 
services are available as long as materials 
can be obtained.

ABB cannot guarantee availability of life 
cycle services for technical reasons or 
within reasonable cost.

Limited life cycle services

Caution! A drive entering the limited or obsolete phase has limited repair options. This 
may result in unpredictable process downtime. To avoid this possibility, the drive should 
be kept in the active or classic phase. 

Limited

Obsolete

Active

Classic

The drive, with complete life cycle ser-
vices, is available for purchase.

The drive, with complete life cycle 
services, is available for plant extensions.

Complete life cycle services

To ensure the availability of complete life cycle services, a drive must be in the active or 

classic phase. A drive can be kept in the active or classic phase by upgrading, retrofi t-

ting or replacing. 

Secure uptime throughout the drive life cycle

ABB follows a four-phase model for managing the life cycles 
of its drives. The life cycle phases are active, classic, limited 
and obsolete. Within each phase, every drive series has a 
defined set of services. 

Examples of individual services are drive selection and di-
mensioning, installation and commissioning, preventive and 
corrective maintenance, remote monitoring and intelligent 
diagnostics, technical support, upgrade and retrofit, replace-
ment and recycling plus training and learning. 

In the active phase the drive is in serial production. The drive, 
with complete life cycle services, is available for purchase. 
In the classic phase, the serial production of the drive has 
ended. The drive, with complete life cycle services, is avail-
able for plant extensions. 

In the limited phase, the drive is no longer available. The life 
cycle services are limited. Spare parts as well as maintenance 
and repair services are available as long as materials can be 
obtained. 

In the obsolete phase, the drive is not available. ABB can-
not guarantee availability of services for technical reasons or 
within reasonable cost. 

To ensure the availability of complete life cycle services, ABB 
recommends that a drive is kept in the active or classic phase 
by upgrading, retrofitting or replacing. 

In the classic phase ABB carries out an annual review for 
each drive life cycle plan. Should any changes to the availabil-
ity or duration of the services be necessary, ABB gives a life 
cycle announcement indicating eventual change of life cycle 
phase and/or any change in the duration of services. 
In the limited phase, ABB issues a life cycle phase change an-
nouncement, half a year prior to shifting the product into the 
obsolete phase.

Maximizing return on investment

The four-phase life cycle management model provides cus-
tomers with a transparent method for managing their invest-
ment in drives. In each phase, customers clearly see what 
life cycle services are available, and more importantly, what 
services are not available. Decisions on upgrading, retrofitting 
or replacing drives can be made with confidence.
