E-1073 Datasheet, PDF (4/6 Pages) ETAL Group – Battery and cable protection for all types of vehicle (including electric), battery powered systems.

Battery Isolation Switch E-1073-437
Typical applications
For road vehicles, e.g. buses and coaches
Series E-1073-1102-437...
For rail vehicles, e.g. underground carriages
Series E-1073-1233-437...
In this application, the E-T-A combined battery switch/circuit
breaker has several functions:
In this application, the E-T-A combined battery switch/circuit breaker
has two functions:
l High performance circuit breaker rated at 240 A, providing
l High performance circuit breaker providing battery and cable

l Isolation switch, for ON/OFF operation (e. g. for main system
l Isolation switch between battery and loads.

l Remote control via external, low-current circuit.
In this application, an ON/OFF remote control switch can be provided

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