The Off Road Living Heavy Duty Relay 12V 100A is a purpose-built switching relay designed to handle the demanding electrical loads found in caravans, 4WD vehicles, camper trailers, and motorhomes. Rated at a full 100 amps continuous at 12V DC, this relay features a sealed, vibration-resistant construction that stands up to the corrugated tracks, creek crossings, and rough terrain that Australian off-road travellers encounter every day. Its low-resistance contacts minimise voltage drop, protecting sensitive 12V accessories and ensuring consistent performance across the full load range.

Ideal for Australian caravan and 4WD enthusiasts who need reliable switching control for high-current accessories — think winches, compressors, dual-battery systems, fridge circuits, lighting bars, and electric brakes — this relay is a go-to component for custom 12V electrical builds. Whether you're wiring a touring rig from scratch or upgrading an existing setup in your RV or off-road camper, the Off Road Living 100A relay delivers the grunt needed to switch heavy loads safely, protecting your wiring and accessories from the heat and vibration of life on the road in Australia's harshest conditions.
