QF240 - 40Amp Circuit Breaker

QF240 - 40Amp Circuit Breaker

The QF240 is a 2-pole, 40-amp QPF ground fault circuit interrupter (GFCI) circuit breaker designed for you to use in compatible 120/240VAC electrical distribution systems. Featuring Class A ground-fault protection with a 5mA trip threshold, this plug-on breaker helps you protect people from electrical shock by interrupting power when a ground fault is detected. Its 10kA interrupting capacity (AIC) makes it suitable for branch circuit protection in residential and light commercial applications where GFCI protection is required by code. Built for dependable operation and designed to last, the QF240 provides the correct form, fit, and function for maintaining or replacing compatible breakers in existing panelboards without altering the original system design. The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment within its specified ratings.
