Pollak 54-852PL 150 Amp Type I High Amp Circuit Breaker – 30V DC, Waterproof Plastic Housing

Maximum-Duty Circuit Protection for High-Draw Systems

The Pollak 54-852PL is a powerhouse in the high-amperage circuit breaker market. Delivering a massive 150 Amp capacity, this single-pole thermal breaker is engineered to handle the most demanding electrical loads found in heavy-duty trucks, emergency vehicles, and marine applications. Designed for 12V to 30V DC systems, it provides the ultimate failsafe for your high-power accessories.

Durability Meets Advanced Safety

Built with a UL-rated 94V-0 thermoset plastic housing, the 54-852PL is designed to thrive where metal breakers fail. The non-conductive, corrosion-proof body ensures that even in the event of a loose terminal, there is no risk of short-circuiting against the housing.

• Ignition Protected: Certified to SAE J1625 and J1171 standards, making it safe for use in engine compartments, battery boxes, and near fuel sources.

• Weatherproof & Splashproof: The rugged housing is sealed to prevent ingress from water, dust, and road salt, ensuring a long service life in exposed mounting locations.

• Stable Surface Mounting: The heavy-duty two-hole base provides a secure mount that resists the intense vibrations of diesel engines and rough terrain.

Type I Automatic Reset (Cycling) Minimize downtime with the Type I auto-reset functionality. In the event of an overcurrent, the breaker trips to protect the circuit and automatically resets once it reaches a safe operating temperature. This is a critical feature for high-draw systems where manual access is difficult or intermittent surges shouldn't leave you stranded.
