QC1040 - 40 Amp Circuit Breaker

QC1040 - 40 Amp Circuit Breaker

The QC1040 is a 40 Amp, single-pole Type QC circuit breaker designed for your 120VAC electrical systems. It uses a thermal magnetic trip to help you protect circuits from overloads and short circuits during normal operation. With a 10k A.I.C. interrupting rating, it's suitable for applications where that level of fault protection is required. This breaker also carries a Quicklag HACR rating, making it appropriate for qualifying heating, air conditioning, and refrigeration equipment. Its Cable-In/Cable-Out design offers a familiar connection style for compatible installations. Whether you're replacing a worn breaker or matching the specifications of an existing electrical system, checking the part number, amperage, pole configuration, and breaker type is the best way to confirm compatibility. The QC1040 is rated for operation in 40°C ambient temperatures and fits compatible Type QC equipment.
