QCF2040 - 40Amp Circuit Breaker

QCF2040 - 40Amp Circuit Breaker

The QCF2040 is a 40-amp thermal-magnetic circuit breaker for 120/240 VAC. It is built for installations that require a Type QCF breaker and has a 10 kA interrupting rating. The thermal magnetic trip mechanism responds to both overloads and short circuits, helping you protect connected equipment and wiring. This breaker uses a face-mount configuration with cable-in/cable-out connections and is rated for operation in 40°C ambient conditions. It is also HACR-rated, making it compatible with heating, air conditioning, and refrigeration equipment. As with any replacement breaker, confirm that the breaker type and electrical ratings match the equipment before installation.
