Pollak 54-720 20 Amp Type II Modified Reset Circuit Breaker – Blade Terminal Plug-In

Upgrade your vehicle's electrical reliability with the Pollak 54-720 20 Amp Circuit Breaker. Engineered as a direct, plug-in replacement for standard 20A automotive blade fuses, this Type II breaker provides advanced "Modified Reset" protection for your vehicle's 12V DC systems.

The 54-720 is a Non-Cycling (Type II) breaker, which is a critical safety feature for modern truck electronics. When a fault or overload occurs, the breaker trips and remains open as long as the circuit is powered. It will only reset once the operator turns off the power source (such as the ignition or accessory switch), allowing the internal components to cool. This prevents the "auto-cycling" common in Type I breakers, which can lead to heat fatigue in wiring and damage to sensitive equipment like heater blowers, power window motors, and auxiliary power outlets. With its standard blade terminal design, it installs instantly into your existing fuse panel, eliminating the need to carry spare fuses and reducing diagnostic downtime.

Key Features:

• Type II Modified Reset: Stays tripped until power is removed, ensuring the fault is safely addressed before the circuit re-energizes.

• 20 Amp Direct Replacement: Specifically designed to fit standard automotive blade-style fuse holders (ATO/ATC style).

• Non-Cycling Protection: Prevents repetitive electrical surges, protecting motors and wiring from overheating.

• Rugged Construction: Built with a durable metal case to withstand the high-vibration environments of heavy-duty trucks and trailers.

• Reusable Efficiency: Offers a permanent solution to blown fuses, making it an excellent tool for troubleshooting intermittent electrical issues.
