Overview
A 40A manual-reset circuit breaker for 12–48V DC systems, sized for fridges, diesel heaters, smaller inverters and the feed into a distribution panel. It resets by hand, so a fault costs you a button press rather than a spare fuse you did not pack.
The F-style base mounts on the surface, the body seals to IP67, and it is ignition protected — so it can live in an engine bay or battery box where fuel vapour is a possibility. The push button opens the circuit on demand for isolation; resetting is a separate, deliberate action. Size the cable to the breaker, not to today's load: the breaker protects the cable, so the cable has to carry what the breaker will pass.
