Enhanced Safety with Modified Reset Protection
The Pollak 54-950 is a high-quality, Maxi-style circuit breaker designed for 12VDC systems that require a higher level of safety than standard cycling breakers. Rated at 20 Amps, this breaker is a direct OEM-style replacement for Maxi-blade fuses in Ford, Paccar, and Freightliner heavy-duty vehicles.

Type II "Modified Reset" Functionality
Unlike Type I breakers that cycle on and off, the 54-950 features Type II Modified Reset technology. When a fault occurs, the breaker trips and remains open as long as the circuit is powered. It will only reset once the power is disconnected or the ignition is turned off, preventing the continuous "on-off" cycling that can lead to heat buildup or electrical wear in sensitive truck circuits.

Direct Plug-In for Professional Power Distribution
Designed with the standard Maxi-blade footprint, the 54-950 fits perfectly into existing power distribution centers and fuse blocks. Its metal housing and precision internal components ensure it handles the high-vibration environment of a heavy-duty chassis or engine bay far better than a standard plastic fuse.

Key Features & Benefits:

Type II Modified Reset: Remains open after tripping for safer troubleshooting—no automatic cycling.
Maxi-Style Blade Format: Fits standard 29mm x 8.9mm Maxi-fuse slots.
OEM Compatibility: Common replacement part for Freightliner, Paccar, and Ford Class 8 trucks.
