The 285-Series surface mount circuit breakers from Blue Sea Systems provide combined switching and circuit protection in one unit. Their IP67 rated design makes them fully waterproof and they are ignition protected, meaning they are safe for marine use around fuels on boats and in vehicles.

They have manual trip and reset functions so they can be used to switch/isolate the circuit if required, and the visible reset lever provides a clear indication of when the circuit is open or tripped. The 'trip-free' design also ensures that the circuit cannot be held 'ON' after a trip has occurred.

Available in ratings from 25-150A with a 3000A interrupt capacity (@48V), these breakers are suitable for a wide range of applications where a medium to high current draw is expected. Note: do not use as a switch where high inrush currents are expected.

Cable connections are via M6 studs on the front of the unit and tethered caps are provided to prevent accidental shorts.

Further information

Note that the connection studs are marked BAT and AUX. It is important for correct operation of the circuit breaker that the battery side is connected to BAT and the load side is connected to AUX.
