Relays

Long wire runs and high current loads steal power and cook switches. We carry relays so you can move the switching close to the load for lower resistance and better uptime in vehicles, trucks and equipment. Choose NO, NC or change-over for the circuit, micro ISO for tight fuse boxes with spike protection, weatherproof for exposure and high-capacity when amps climb. Connectors, brackets and terminals finish the job.

Standard Capacity Relays
Standard Capacity Relays
Relays reduce the length of the wire lead between equipment and the switching mechanism, minimizing resistance and ensuring more power is available. All relays have push-on type terminals. Normally Open (NO) SPST relays close the connection when current is sent, while Normally Closed (NC) SPST relays open the connection. Change-Over Relays (NO/NC) are SPDT type, switching between circuits. Rated at 30 amp for 250,000 cycles, with a 40 amp capacity for 100,000 cycles.
