Cat® Relay when gets current, it energizes an electromagnet. The electromagnet closes open contacts, to energize a circuit. Cat® Relays are switches controlled by electrical power, like another switch, computer or control module. The purpose of an automotive relay is to automate this power to switch electrical circuits on and off at particular times. Quality you expect for your rugged work environment. Cat® Relays are manufactured to precise specifications and are built for durability, reliability, productivity.

Application:
Most common application of automotive relays is to switch a high current circuit using a low current circuit. This application comes into play whereby an in-line switch does not have the capacity to handle the current required to switch a high current electrical system. Consult your owner's manual or contact your local Cat® Dealer for more information.
