QC3050H - 50 Amp Circuit Breaker

QC3050H - 50 Amp Circuit Breaker

If your panel calls for a QC3050H, this 3-pole, 50-amp Type QC circuit breaker offers the electrical protection needed for compatible 240VAC systems. It uses a thermal magnetic trip unit, so it responds to both overloads and short circuits without relying on separate protection devices. The breaker carries a 10kA interrupting rating at 240VAC and is built with a cable-in/cable-out configuration. It is also HACR rated, making it suitable for approved heating, air conditioning, and refrigeration equipment. Whether you're replacing an existing breaker or completing a repair, matching the part number and electrical ratings is the best way to ensure proper fit and performance.
