Pollak 54-956 ATO-Style 30 Amp Circuit Breaker – Type II Modified Reset (Ford HD 8)

High-Capacity Protection for Ford Heavy-Duty Electrical Systems
The Pollak 54-956 is a premium 30 Amp circuit breaker built in the standard ATO/ATC footprint. Specifically engineered to meet the rigorous demands of Ford HD 8 series vehicles and heavy-duty commercial fleets, this breaker serves as a durable, resettable alternative to standard 30A blade fuses in 12VDC systems.

Type II Modified Reset: Advanced Circuit Safety
Safety is critical when managing 30 Amp loads. The 54-956 features Type II Modified Reset technology, which provides superior protection over standard cycling breakers. When a fault is detected, the breaker trips and remains open as long as power is being supplied. It will only reset once the power source is turned off or the load is removed. This "non-cycling" behavior prevents continuous arcing and protects your truck’s wiring harness from the cumulative heat damage caused by persistent shorts.

Rugged Construction for Commercial Use
Built with a robust metal housing and high-quality internal bimetal components, the 54-956 is designed to handle the high-vibration environment of vocational trucks and long-haul rigs. Its standard ATO blade format allows for a direct plug-in installation into most existing power distribution centers and fuse blocks.
