Jaycar 50A 12VDC Chassis Mount Auto Reset Circuit Breaker – Single Pole Thermal Protection

Running a higher-draw load on your 12V system – maybe a heavy-duty compressor, a large inverter feed, or a dual-battery setup – and you want protection that doesn't mean digging through a drawer of spares. This Jaycar 50A single-pole thermal breaker bolts to a flat panel, trips when current exceeds 50A, cools, and resets on its own. One less thing to remember before you fire up the engine. RRP $18.64.
