E-1073 Datasheet, PDF (1/6 Pages) ETAL Group – Battery and cable protection for all types of vehicle (including electric), battery powered systems.

Battery Isolation Switch E-1073-437
Description
Single pole circuit breaker type 437 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.
Typical applications
Battery and cable protection for all types of vehicle (including electric),
battery powered systems.
