Q24040 - Quaplex 40/40 Circuit Breaker

Q24040 - Quaplex 40/40 Circuit Breaker

Looking for a Q24040 circuit breaker to match an existing application? This 40-amp Type QT quadplex breaker is designed for compatible 120/240 VAC electrical panels and has a 10 kA I.C. rating. Its quadplex layout makes good use of panel space, which can be particularly helpful when you're working with a panel where every available position counts.

The Q24040 uses a plug-in connection and measures 3.13 inches high, 2 inches wide, and 2.56 inches deep. It's also HACR-rated and carries a 40°C rating. That combination makes it suitable for a range of compatible electrical applications, including qualifying heating, air-conditioning, and refrigeration equipment.

If you're replacing an existing breaker, don't rely on amperage alone. Check the part number, breaker type, voltage, interrupting rating, and panel requirements to make sure the Q24040 is the correct match for your application.
