QC3020H - 20 Amp Circuit Breaker

QC3020H - 20 Amp Circuit Breaker

The QC3020H is a 3-pole, 20-amp thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection for your compatible electrical distribution systems. Built as a Type QC Quicklag HACR-rated breaker, it combines reliable circuit protection with a convenient cable-in/cable-out configuration, making it well-suited for commercial, industrial, and light industrial electrical applications. Its 10kA interrupting capacity at 240VAC helps you protect connected equipment from damaging fault currents, while the thermal-magnetic trip mechanism responds effectively to both sustained overloads and instantaneous short circuits. Rated for operation in 40°C ambient environments, the QC3020H is an excellent choice for maintaining electrical system safety, minimizing downtime, and supporting long-term performance in demanding installations.
