C-Series Flat Rocker Circuit Breaker - Single Pole - 5A


Circuit breaker protection with a modern look

You will rarely find a breaker panel that will come pre-installed with the same circuit protection your system requires. Each electrical system is unique to the boat and the boat owner. Circuit breakers will inevitably have to be changed to meet the demands of existing or changing electrical loads. Blue Sea Systems makes it simple.

C Series Circuit Breakers combine circuit protection and switching in a flat rocker switch and are designed to fit Blue Sea Systems 360 panels and modules included in SMS enclosures. Quick changes to the proper protection can be made by removing a cover to an open position or changing an existing switch; the mounting holes and fasteners are matched to make it quick and easy.

All C series circuit breakers are now CE marked. These circuit breakers can handle the short starting current surges found in electric motors and other appliances without tripping. Your need added safety, and a Trip-Free function prevents the rocker. These single pole circuit breakers are available in protection ratings from 5A-100A to suit different circuit protection needs.
