Pollak 54-321PL 20 Amp Type 3 Manual Reset Maxi-Style Blade Circuit Breaker

Upgrade your vehicle's power distribution with the Pollak 54-321PL 20 Amp Maxi-Style Circuit Breaker. This heavy-duty Type 3 Manual Reset breaker is designed to plug directly into standard Maxi-blade fuse blocks, providing a reusable and safer alternative to traditional one-time fuses.

Unlike automatic breakers that cycle power, the 54-321PL trips and remains "off" following an electrical overload. A manual reset lever must be depressed to restore power, ensuring you have the opportunity to identify and clear the fault before re-energizing the circuit. This makes it an essential safety component for protecting 12V DC auxiliary power feeds, interior heater fans, and lighting controllers.

Constructed with a high-impact, non-conductive plastic housing, this 20 Amp breaker is built to withstand the vibration and thermal stress common in heavy-duty trucking, construction, and agricultural machinery.

Key Features:

• Type 3 Manual Reset: Stops the circuit from cycling; power remains disconnected until the user manually resets the breaker.

• Maxi-Style Blade Format: Fits all standard Maxi-fuse holders and power distribution modules.

• 20 Amp Precision Protection: Ideal for mid-range 12V and 24V DC electrical accessories and motors.

• Durable Plastic Housing: Color-coded for fast amperage identification and designed for high-vibration environments.

• Visual Trip Indicator: The reset lever provides a clear visual signal that the breaker has tripped, simplifying troubleshooting.
