Isolator Relay 100A


Intellitec's Isolator Relays are used to isolate two battery systems. This innovative and cost effective design allows the relay to operate with almost no voltage across contacts and can handle currents up to 100 Amps. The Intellitec Isolator Relay works with most common gasoline engines. The relay can be manually switched through a dash mounted switch or coupled with Intellitec's Isolator Controls for fully automatic functioning.
