Technical data – Electronic module

Single pole circuit breaker type 437 or single/two pole isolation switches
types 921/922 featuring an additional electronic function module which
limits the duration of the supply to the remote disconnect and re-
connect coils, avoiding damage in the event of unusual operating
circumstances. Available with undervoltage monitoring option to
protect batteries from the effects of deep discharge, status output for
undervoltage, auto reset feature.

Battery and cable protection for all types of vehicle (including electric),

Technical description

E-T-A circuit breaker/battery isolation switches combined with electronic
control unit E-1073 will meet a wide range of requirements.

Circuit breaker/battery isolation switches

The main switching contacts will open the plus, the minus or both
poles according to model and application.

●

Series E-1073-....437

Single pole thermal-magnetic circuit breaker for current ratings up
to 240 A, to protect the vehicle electrical system from overloads
and short circuits.

●

Series E-1073-...-921

Single pole battery isolation switch for current ratings up to 240 A.

●

Series E-1073-...922

Double pole battery isolation switch for current ratings up to 120 A.

Electronic control unit

An electronic control unit enables the basic on/off function and two
additional functions. The system voltage is connected across terminals
+UB/-UB to provide the supply to the control unit and a feed is taken
from +US1 for the remotely sited operating switch(es). The quiescent
current drain is typically less than 1 mA, with a short duration excursion
during excitation of the ON/OFF coils.

Basic function

Switch ON/OFF

Operation of the ON control switch will energise the switch-on coil for
approximately 100 ms causing the main switching contacts to latch
closed. Operation of the OFF control switch will cause the disconnect
coil to trigger the release of the switching mechanism within
approximately 20 ms. Both coil circuits are current limited to prevent
damage through overheating.

Manual operation

An optional external operating knob is available to provide manual
control in addition to electrical ON/OFF operation.

Reverse polarity protection

In the event of reverse polarity connection, the electronic control unit
will immediately operate the battery switch to isolate the entire
electrical system. The circuit breaker will trip after a short delay to
protect the operating coils and must be re-set once the fault has been
corrected.

Control functions

Type 1 E-1073-.1.. with ON/OFF switch

ON/OFF control switch input (»E/A«)

The battery isolation switch can be operated on or off by an external
control switch to plus.

Undervoltage protection (optional)

This optional feature protects the battery from deep discharge
should electrical loads be left on.
The battery is automatically disconnected whenever the voltage
falls below a critical value for more than 40 s. The unit is reset by
operation of the control switch. Sustained undervoltage after
reconnection causes the unit to disconnect again after approx. 40 s.

Overriding the undervoltage protection (»U-AUS«)

Undervoltage protection may be overridden if required by
connecting control output »U-AUS« to plus terminal or terminal 15.

Undervoltage status output (»UST«)

Undervoltage is signalled immediately via the minus-switching,
short-circuit proof transistor output (2 W lamp load).

Auto reset (»A-W«), optional with series 921 and 922

Immediate reset after unwanted mechanical disconnection (e.g.
upon excessive vibration) is provided by the integral electronic
control.

Type 2 E-1073-.2.. with ON/OFF button

ON/OFF control inputs (»T-ON/T-OFF«)

ON/OFF function is provided by two external switches with a
central control function, i.e. several systems can be operated
simultaneously.

Additional control current supply (»+US2«)

If several circuit breakers/battery isolation switches are operated
in parallel, switches can be supplied with control current from any
of the electronic control units available. This power source is
short-circuit proof, protected from noise voltages and will operate
for 20 inputs.

Additional control input »ON/OFF Test« (»E/A«)

This control input can be used for maintenance purposes. The
battery isolation switch is switched on when plus voltage is applied,
and switched off when plus voltage is removed.

Note

The circuit breaker should be in the OFF condition when connecting or
replacing the battery.

Observe instructions for installation!

For road vehicles, e.g. buses and coaches

Series E-1073-1102-437-B3-K12-07-Si01-240 A

In this application, the E-T-A combined battery switch/circuit
breaker has several functions:

●

High performance circuit breaker rated at 240 A, providing
battery and cable protection from overloads and short circuits.

●

Isolation switch, for ON/OFF operation (e.g. for main system
disconnection).

●

Remote control via external, low-current circuit.

●

Undervoltage protection from battery deep discharge should
electrical loads be left on.

●

Early under voltage signalisation via a warning lamp
(undervoltage status output), located as required.

●

Undervoltage operation can be overridden if required.

●

Auxiliary contact to disconnect the generator field.

●

Reverse polarity protection through immediate disconnection
of the entire vehicle electrical system if the battery is
incorrectly connected.

These functions allow the number of components and cables
required to be reduced, with significant space and weight saving
benefits.

For rail vehicles, e.g. underground carriages

Series E-1073-1233-437-K60-06-Si01-200 A

In this application, the E-T-A combined battery switch/circuit
breaker has two functions:

●

High performance circuit breaker providing battery and cable
protection from overloads and short circuits.

●

Isolation switch between battery and loads.

In this application, an ON/OFF remote control switch can be provided
in both the first and last carriages. This will enable all batteries to be
disconnected from the power distribution system by the operation
of one control, irrespective of its location. In the same way, all
batteries can be re-connected by the operation of a single control
switch.
This is extremely helpful during coupling/de-coupling of carriages
for example. In addition the E/A test input permits the operation of
individual battery switch/circuit breakers during maintenance.
