Osculati Panel Mount Watertight Circuit Breakers for Windlass & Bow Thruster (40–200A)
The Osculati Panel Mount Circuit Breaker range is designed to provide reliable overload protection and manual power isolation for marine windlasses, bow thrusters, and other high-current onboard electrical systems. These thermal circuit breakers combine the functions of a resettable fuse and an ON/OFF disconnect switch in a single waterproof unit.
Manufactured in the USA in accordance with SAE J1171 and CE28846 Vapor Proof standards, the breakers are built for demanding marine environments and offer approximately 3,000 operating cycles. The enlarged 5/16" electrical terminals simplify installation of larger marine cables, while the recessed panel-mount design requires only a simple circular mounting hole.
With an IP66 waterproof rating and support for electrical systems up to 48V DC, these circuit breakers are suitable for protecting electric windlasses, bow thrusters and other heavy-duty DC equipment. Versions rated from 100A to 200A can also be used as general battery disconnect switches.
