Q24040CT - Quadplex 40/40 Circuit Breaker

Q24040CT - Quadplex 40/40 Circuit Breaker

If you're replacing a breaker and Q24040CT is the part number you need, it's worth checking the details before making the swap. This is a 40-amp Type QT quadplex circuit breaker with a plug-in design, rated for 120/240 VAC and 10 kA ICC. It measures 3.13 inches high, 2 inches wide, and 2.56 inches deep, so you get a lot of functionality in a relatively small amount of panel space. The Q24040CT also has common-trip operation and carries an HACR rating for qualifying heating, air-conditioning, and refrigeration applications. As with any replacement breaker, don't go by amperage or appearance alone. The breaker type, voltage, interrupting rating, configuration, and the panel it's going into all need to meet the job's requirements.

Key Features and Benefits

Material Compliance and Certifications

• The information available for the Q24040CT indicates it is HACR-rated. That rating is important when the breaker is being considered for qualifying heating, air-conditioning, or refrigeration equipment.
• Other certification and material compliance information was not included in the provided specifications. Rather than assume, it's better to check the markings on the actual breaker and its supporting documentation whenever a job requires a specific listing or compliance standard.

Where It Works Best

• This breaker is intended for compatible electrical panels and load centers that accept Type QT plug-in breakers. The quadplex layout is particularly handy in applications where panel space is tight and this exact breaker configuration is required.
• The Q24040CT may also be appropriate for qualifying HVAC and refrigeration equipment where a 40 amp, 120/240VAC, HACR-rated breaker with a 10k AIC rating meets the system requirements.
