More about our Relays
Automotive and industrial relays are electrically operated switches that allow a low-current control circuit to switch a much higher-current load circuit — enabling switches, ECUs, and control modules to safely manage high-current accessories like lighting, winches, pumps, fans, and solenoids without routing heavy current through delicate switch contacts. In mine-spec vehicles and heavy industrial equipment, professional-grade relays are essential for the reliable operation of high-draw accessories and critical systems that must perform consistently in extreme environmental conditions.
Relays are available in a range of contact ratings, coil voltages, and mounting configurations. Standard automotive relays handle loads up to 30–40A for common accessories, while heavy-duty relays with ratings from 100A to 200A+ are required for high-current applications like winches, air compressors, and major lighting arrays. Sealed relays provide environmental protection for exposed installation locations, while standard relays offer cost-effective solutions for protected interior installations. Relay bases, sockets, and fuse/relay combo units allow for clean, accessible relay installations in junction boxes and distribution panels.
Minespec NSW stocks relays across a range of contact ratings and configurations suited to mining vehicle and industrial equipment applications. Our range includes standard ISO automotive relays, high-current heavy-duty relays, sealed relays, and relay accessories — providing everything needed for professional relay circuit design and installation.
