Description
The Blue Sea Systems 187-Series Circuit Breaker – Panel Mount 150A (7048) is a heavy-duty marine circuit protection device that combines manual switching and overcurrent protection in one compact unit. Designed for demanding marine electrical installations, it helps protect electrical circuits against excessive current while providing convenient manual operation and reset.
The waterproof construction and ignition-protected design make this circuit breaker suitable for installation aboard petrol-powered boats when installed in accordance with the manufacturer’s instructions. Its large operating lever provides clear manual control, while the lever’s vertical or horizontal orientation indicates the breaker’s trip status.
The Type III trip-free mechanism prevents the breaker from being held in the ON position during a fault condition. Recessed mounting holes provide a clean panel finish, and the generous clearance around the terminal studs accommodates heavy-gauge cable lugs.
