Pollak 54-120 20 Amp Type 1 Automatic Reset Circuit Breaker – Heavy-Duty Metal Housing

Maintain maximum uptime for your electrical systems with the Pollak 54-120 20 Amp Circuit Breaker. This rugged, Type 1 "Automatic Reset" breaker is specifically engineered for the high-demand environments of commercial trucking, agriculture, and construction equipment. Unlike traditional fuses that require manual replacement after a trip, the 54-120 automatically resets once the overcurrent condition is resolved, keeping your auxiliary power, lighting, and small motors running without interruption.

Built with a heavy-duty metal housing, this breaker offers superior heat dissipation and impact resistance compared to plastic alternatives. Its zinc-plated steel construction protects internal components from vibration and mechanical wear, making it the preferred choice for chassis-mounted electrical clusters and under-hood applications.
