Blue Sea SystemsA-Series Toggle Single Pole Circuit Breakers

This is an awesome switchable circuit breaker. The switch allows me to turn on/off an inverter that I can not access the built in switch. The breaker holds its rated 50 amps for as long as I have run that much power through it. It will trip as designed at 60 amps. I tested that multiple times. Much better than some of the no-name circuit breakers that did not trip at all, in an over amperage scenario.

This was easy to wire up and provided a circuit breaker and on-off switch for my ebike project. My 48V battery only had the BMS protection but no switch. This was the simplest switch I could find and once I hooked it up using the non-sparking XC90 connector, this made the install a breeze. Small and compact that I could tuck it away on my Specialized Enduro frame.

Waterproof, compact size (approximately 2in x 2in by 1/2) and 50 amp breaker is perfect for my e-bike set up - I can even rig up a pull string for an emergency kill switch in the event the throttle sticks wide open in a malfunction.

I had a customer who's 1985 Bluewater houseboat kept tripping main breakers. I bought four of these replacement breakers and installed them a month ago. Customer is happy. No more coming home to find the AC not working because of tripped breakers!
