Pollak 54-940 Sealed 40 Amp Circuit Breaker – Type I Automatic Reset with 12-Inch Wire Loop

Reliable Overcurrent Protection for Rugged Environments
The Pollak 54-940 is a high-performance, Type I sealed circuit breaker designed to provide dependable protection for heavy-duty electrical systems. Engineered for 12VDC applications, this 40 Amp breaker is built to withstand the harshest conditions, making it an essential component for trucks, RVs, buses, and marine equipment.

Sealed Design for Maximum Durability
Unlike standard breakers, the 54-940 features a sealed housing specifically designed for exposed applications. Whether your vehicle is facing moisture, dust, road salt, or oil, this unit remains protected, ensuring consistent performance and preventing premature electrical failure.
