Description
The Blue Sea Systems 187-Series Circuit Breaker – Panel Mount 100A (7044) is a heavy-duty marine circuit protection device designed to combine manual switching and overcurrent protection in one compact unit. It helps protect electrical circuits against excessive current while providing convenient manual operation and reset.
Built for demanding marine environments, this circuit breaker features waterproof construction and ignition protection, making it suitable for installation aboard petrol-powered boats when installed in accordance with the manufacturer’s instructions.
The Type III trip-free mechanism ensures the breaker cannot be held in the ON position during a fault condition. Its large operating lever provides straightforward manual control, while the vertical or horizontal lever orientation indicates trip status. Recessed mounting holes allow for a clean panel installation, and generous clearance around the terminal studs accommodates heavy-gauge cable lugs.
