Built for tough 12/24V touring and marine systems, the Enerdrive EN-RCB40 is a compact, manual-reset, surface-mount circuit breaker that doubles as a convenient on/off isolation point. It’s ignition protected (SAE J1171) and weather-resistant, with a trip-free mechanism so it can’t be held closed after a fault. The visible reset lever makes fault-finding simple, and the standard footprint is a drop-in replacement for 185/285-series breakers—perfect for DC chargers, solar feeds, fridge circuits, winch feeds (light duty), and accessory distribution.
