The Mini Relay 12V 30A with Fixing Bracket is a compact, heavy‐duty switching relay for 12 V DC electrical systems. Built by Durite with a tough black plastic body and an integral metal mounting bracket, it controls higher‐current loads using a low‐current trigger, protecting switches and wiring from overheating.

Designed as a reliable replacement for Lucas SRB520, it suits cars, vans, light plant, agricultural and garden machinery that run 12 V electrics. Use it to switch fans, pumps, lighting, beacons and other auxiliary circuits within the stated 30 A rating.
