Blue Sea 7039 50A 187-Series Panel Mount Breaker

The Blue Sea Systems 7039 is a 50 amp panel mount breaker in the 187 Series, rated to 48 volts DC.

This is the panel mount version of the 50 amp rating, going through a bulkhead rather than onto its face. The round self-trimming case is what makes that quick. A standard hole saw cuts the opening and the case finishes its own edge, so there is no bezel and no filing.

Fifty amps suits a sub-panel feed or a heavier accessory circuit, sized to what the cable can carry rather than to the load on the end. The thermal bi-metal element tolerates startup surge instead of tripping on it, so this style suits motor and compressor circuits.

Interrupt capacity is 5,000 amperes at 12 volts DC, 3,000 at 24 and 1,500 at 42, in Type III class with manual reset and trip free operation. Recessed mounting holes keep the finished face clean, 5/16 studs take heavy gauge lugs, and it is waterproof and ignition protected to SAE J1171. Explore more marine circuit breakers.
