A simple circuit breaker board with isolator switch designed to protect inverters and AC mains equipment from shorts, surges and ground leaks using a 30mA RCD and a choice of MCB trip current ratings.
The IP55 protective case and clear hinged lid allows for easy monitoring of any faults while being resistant to tampering. Knockouts included on the top and bottom of the case also make it easy to protect incoming our outgoing cables with either 20mm or 25mm cable conduit.
Circuit breakers are rated at 1, 2 and 4 amps which at standard UK domestic mains voltages equates to 240, 480 and 960 watts. These power ratings can be matched to any 250, 500 or 1000 watt inverter respectively, which protects against overloading, accidental grounding and extended periods of peak power draw.
