Pollak 54-876PL 250 Amp Type III Manual Reset Circuit Breaker – Surface Mount, Waterproof Plastic

The Pollak 54-876PL is a robust 250 Amp Type III Thermal Circuit Breaker, designed to safeguard the most demanding electrical circuits in your vehicle or vessel. As the highest amperage model in the Pollak plastic housing series, it is the go-to choice for protecting primary power feeds, massive inverter banks, and high-capacity hydraulic systems found in the trucking and marine industries.

Safety is critical when handling 250 Amps. The 54-876PL features a high-visibility manual reset lever that pops out to show a tripped condition instantly. Because it is a "Type III" switchable breaker, it also provides the functionality of a manual kill switch, allowing you to isolate the circuit during maintenance or when the vehicle is in long-term storage to prevent parasitic battery drain.

Engineered for the "hot zones" of trucks and boats, this breaker is housed in a thermoset plastic (UL rated 94V0) that resists corrosion and high temperatures. It is fully sealed, splash-proof, and dust-proof, ensuring reliable operation even when exposed to road spray or engine bay debris. It is also ignition protected, making it safe for use in gasoline engine compartments.
