Power relay and socket assembly with
convenient mounting flange

Relays

Power relays are switches that allow a small amount of power to operate or switch on a relatively powerful device.

Recommended when installing high-performance fans, pumps, or any other 12V accessory, sūsa power relays provide safe circuit management of high amounts of amperage and automatic control of electrical devices.

sūsa power relays are supplied as Bosch-type, 5-pin 30/40A power relay and socket assemblies.
