GEBE 991181 Battery Isolator Voltage Sensitive Relay 24V 140A - Made in Germany
This is a premium quality item, made in Germany by IKA under their GEBE brand. GEBE was founded in 1906 and takes its name from their founder's initials, Gotthilf Breining. GEBE was originally a supplier to Bosch, Lucas, Fiat, and others.
This voltage sensitive Relay allows two batteries to be charged at the same time. When the engine starts and the starting battery reaches 27.4V, the relay pulls in, allowing the two batterys (starting and auxiliary) to be charged simultaneously. When the voltage drops below 25.6V, (or the engine has stopped), the relay drops out, separating these batteries. This system isolates the starting battery and prevents it from fully discharging, while protecting sensitive electronic equipment powered by the auxiliary battery from harmful start up voltage spikes.
