Pollak 54-958 Mini-Style 15 Amp Circuit Breaker – Type II Modified Reset (Freightliner HD 8)

Reliable 15A Protection for Freightliner & Modern Fleet Systems
The Pollak 54-958 is a heavy-duty 15 Amp circuit breaker designed in the ultra-compact Mini-blade (ATM) footprint. Specifically engineered to meet the requirements of Freightliner HD 8 series vehicles and modern commercial fleets, this breaker is a high-performance, resettable alternative to standard 15A mini-fuses in 12VDC electrical systems.

Enhanced Safety with Type II Modified Reset
Protect your vehicle’s wiring and sensitive electronic modules with Type II Modified Reset technology. Unlike standard "cycling" breakers that repeatedly attempt to restore power, the 54-958 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 critical for preventing heat buildup and protecting the integrity of your Freightliner's electrical harness during a persistent fault.

Precision Fit for Dense Fuse Panels
The 54-958 features the standard Mini-style format, making it ideal for the crowded power distribution centers and fuse blocks found in late-model truck cabs. Its rugged construction is designed to withstand the high vibration, moisture, and thermal shifts common in vocational trucking.
