Description

The SPF Solar Protection Fuse series has been specifically
designed for the protection of photovoltaic (PV) systems.
This series of Midget style fuses (10 x 38 mm) can
safely protect PV modules and conductors from reverse-
overcurrent conditions.
As PV systems have grown in size, so have the
corresponding voltage requirements. This increase in
system voltage has typically been intended to minimize
power loss associated with long conductor runs. Standard
circuit protection devices are not designed to completely
protect photovoltaic panels. However, the SPF series is
UL Listed to safely interrupt faulted circuits up to this
demanding voltage level.

Features/Benefits

• Meets UL, IEC and VDE photovoltaic standards

•  UL 2579 Listed 1000 Vdc maximum
•  1-30 A ratings available
•  20,000 A Interrupting Rating
•  Both PCB mount and dead-front holder options available

Applications

•  Inverters
•  Combiner boxes
•  Battery charge controllers

Description

POWR-BLOKS

power distribution blocks offer a safe,

convenient way of splicing cables, providing a fixed junction
tap-off point or splitting primary power into secondary circuits.
Lx2xxx-DIN series offers integral DIN-Rail mount and an
optional hinged safety cover.

Optional power distribution block covers provide protection
against accidental shorting between poles caused by
loose wires, tools, or other conductive material. They also
protect personnel from accidentally contacting energized
connectors. To order protective covers, match the number
of poles for the block to the cover.

Applications

•

Solar string

•

Array combiner boxes

•

Inverters

Ampere Ratings

The ampere rating per pole for the power distribution blocks is
based on the line ampacity of 75° C insulated conductors per
NEC

Table 310.16. If 60° C insulated conductors are used,

load must not exceed the ampacity of 60° C conductors.
Use of conductors rated in excess of 75° C is permitted
(for example 90° C), however, load must not exceed the
ampacity of 75° C conductors.

Connectors

Box lug connectors are designed for use with a single,
solid or class B or C stranded conductor. Use of more
than one con ductor per connector opening or use of
extra-flexible, fine-stranded conductors, such as welding
cable, voids the UL Listing and may cause overheating.
Manufacturers of cable ter minations can furnish crimp-on
sleeves for fine stranded conductors which permit these
conductors to be used with box lugs.

TVS (TRANSIENT VOLTAGE SUPPRESSION) DIODES

What Are Voltage Transients?

Voltage transients are unwanted short duration surges of electrical

energy. They may result from the sudden release of previously stored

energy, and can come from internal and external sources. If the

voltage magnitude of the transient is large enough, circuit component

damage or malfunction of the circuit may result.
Transients can occur either repeatedly or as random impulses.

Repeatable transients are frequently caused by the operation of other

system components, such as motors, generators or the switching

of reactive circuit components. Random transients, are often caused

by lightning, electrostatic discharge (ESD), and other outdoor

environment events.

TVS and Solar Inverter Protection

Integration of Transient Voltage Suppression (TVS) components

within solar system designs help to prevent the damaging effects

of transient events and assure compliance to safety and reliability

standards. Solar power inverters are vulnerable to transient voltage

effects and its direct connection to other system components allows

transient voltage transfer. For example:

•

Lightning-induced transient events may pass through the solar

array and outdoor cabling to the inverter.

•

Transients originating from the outside utility power grid may pass

through the main circuit panel and cabling to the inverter.

•

Startup of motorized equipment enable vulnerabilities produced

by repeat load changes.

•

Electrostatic discharge events generated internal and external to

the system may pass between the inverter and sensitive

electronic control equipment.

It is important to build surge withstand ability in the inverter and at

locations before damaging transients may reach sensitive equipment.

Transient Voltage Suppression (TVS) Diodes

TVS Diodes are used to protect semiconductor components from high-voltage transients. Their p-n junctions have a larger cross-sectional area

than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage. Littelfuse supplies TVS Diodes with

peak power ratings from 200 W to 30 kW, and reverse standoff voltages from 5 V to 530 V. For more information visit

Varistor Products

Varistors possess characteristics that divert transient currents away from sensitive components. Littelfuse offers two types:

miniature surface mount Multi-Layer Varistors (MLVs) for small electronics applications and Metal Oxide Varistors (MOVs) for

higher energy applications. For more information visit

Description

The SE-601 is a microprocessor-based ground-fault relay for
ungrounded dc systems. It provides sensitive ground-fault
protection without the problems associated with nuisance
tripping. Ground-fault current is sensed using an SE-GRM
Series Ground-Reference Module—a resistor network that
limits ground-fault current to 25 mA. The SE-601 is used
on ungrounded DC systems ranging from industrial 24 Vdc
control circuits to 1000 Vdc solar and transportation systems.

EL731 SERIES

AC/DC Sensitive Earth-Leakage Relay

Description

The EL731 is a microprocessor-based AC/DC Sensitive
Earth-Leakage Relay that offers complete coverage for all
frequencies from 0-6,000 Hz. Two CTs are required for the
entire frequency range, or one CT can be used for only low-
or high-frequency detection. An RTD/PTC sensor input
allows over-temperature protection. The EL731 offers
metering capabilities, password-protected alarm and trip
settings and optional network communications. It is used to
add low-level ground-fault protection to variable-speed
drives, and to DC currents.
