IMTRA Imtra 150 Amp Windlass Thermal Circuit Breaker - Surface Mount
The Imtra SPA-187150F is a 150-amp Bussmann thermal circuit breaker designed for surface-mount installation in marine windlass systems. Available in 50, 70, 110, and 150A ratings, these breakers automatically interrupt current in the event of an overload or short circuit, protecting the windlass motor and wiring from damage.
The surface-mount configuration allows installation in accessible locations such as near the helm, engine room, or anchor locker. The housing is IP66-rated for use in wet locations.
Connections accept 5/16-inch terminal lugs for large-gauge windlass wiring. Input voltage is rated up to 48VDC, covering 12V, 24V, and 48V DC windlass systems.
A quick reset is accomplished by pressing the breaker manually after the fault condition is cleared. The thru-bulkhead version (SPA-187150L) installs through a 2-1/8-inch holesaw cutout with a faceplate included.
Recommended for Lofrans and Muir electric windlasses.
