Blue Sea Systems 4137 Black Circuit Breaker Boot for Push Button Reset Only Thermal Circuit Breakers

The Blue Sea Systems 4137 is a black replacement mounting boot designed specifically for Thermal Push Button Reset Only circuit breakers. It replaces the standard mounting nut on these breakers, sealing the panel-mount opening around the push button while keeping the breaker accessible for manual reset. The boot is molded from a UV-resistant material engineered to resist discoloration and cracking from prolonged sun exposure, making it well suited to open helm stations, flybridges, and other areas of a boat exposed to weather.

Each retail package contains two boots, so a single order covers a pair of breakers or provides a spare. The boot is compact, sized to fit directly over the push button housing of compatible Thermal Push Button Reset Only breakers without modification to the panel or breaker body. Because it is intended for reset-only push button breakers, it is not designed for toggle-style or trip-free breaker housings.
