Pollak 54-957 Mini-Style 10 Amp Circuit Breaker – Type II Modified Reset (Freightliner HD 8)

Precision Protection for Freightliner & Modern Fleet Electronics
The Pollak 54-957 is a professional-grade 10 Amp circuit breaker designed in the ultra-compact Mini-blade footprint. Engineered specifically for Freightliner HD 8 series vehicles and modern heavy-duty trucks, this breaker provides a resettable, high-reliability alternative to standard 10A mini-fuses (ATM/ATM-style) in 12VDC systems.

Type II Modified Reset for Superior Safety
Protect sensitive truck electronics with Type II Modified Reset technology. Unlike standard Type I breakers that cycle on and off—potentially causing repeated electrical stress—the 54-957 trips and remains open as long as power is applied to the circuit. It will only reset once the power source is disconnected or the ignition is turned off. This "non-cycling" behavior is essential for protecting wiring harnesses from heat buildup during a persistent short circuit.

Space-Saving Mini-Blade Design
The 54-957 features the standard Mini-style format, allowing it to fit into the dense power distribution centers found in modern Freightliner and commercial vehicle cabs. Its rugged construction is built to handle the high vibration and thermal fluctuations of vocational trucking environments.

Key Features & Benefits:

• Type II Modified Reset: Safety-first design stays tripped until power is cut—ideal for troubleshooting.
