Product Overview

Resettable breaker circuit protection that is more affordable and easier to install

Resettable breakers have an advantage over fuses as a method of circuit protection. Both prevent damage to wiring and possible fire in the event of an over-loaded or short circuit, but fuses have to be replaced. A breaker can be reset and restore function when the fault is no longer detected, however, breaker panels are thought to be costly and difficult to install. Blue Sea Systems designed this breaker block to offer the convenience of resettable with the ease of fuse block installation.

Ideal for circuits that are switched elsewhere or do not require switching this block provides positions for twelve circuits and includes a 15A push button resettable breaker to get you started. The remaining slots can be custom tailored by simply plugging in breakers ranging from3A-40A (sold separately). A clear insulating cover provides space for square format labels and satisfies ABYC and USCG requirements. Breakers can be reset without removing the cover through access holes. Breakouts in the cover sides provide wire access to terminal buses. A common ground bus makes grouping ground wires simple and speeds up installation.
