Pollak 54-874PL 120 Amp Type III Manual Reset Circuit Breaker – Surface Mount, Waterproof Plastic

High-Amperage Protection for Demanding Electrical Loads
The Pollak 54-874PL is a heavy-duty 120 Amp Type III Thermal Circuit Breaker, specifically engineered to protect high-draw auxiliary and accessory circuits. Whether you are managing power for a heavy-duty truck fleet, a marine vessel, or a high-end RV electrical system, this 120A breaker provides the ultimate fail-safe against electrical overloads.

Manual Reset & Switchable Functionality
Unlike automatic reset breakers, the 54-874PL features a manual reset lever that provides a clear visual indicator when a circuit has tripped. This "Type III" design allows for manual disconnection, enabling you to use the breaker as a shut-off switch for maintenance or system storage. This ensures that you have total control over your power distribution at all times.

Engineered for Extreme Environments
Built with a rugged thermoset plastic housing (UL rated 94V0), the Pollak 54-874PL is designed to thrive in harsh conditions. It is splash-proof, dust-proof, and ignition protected, making it safe for use in engine compartments, battery boxes, and bilge areas where moisture and heat are constant factors.
