Q24020CT2 - Quadplex 40/20Amp Circuit Breaker

Q24020CT2 - Quadplex 40/20Amp Circuit Breaker

The Q24020CT2 is a Type QT quadplex circuit breaker built for your applications where panel space matters. It combines 40-amp and 20-amp protection in a compact plug-in design that measures only 2 inches wide. The breaker is rated for 120/240 VAC and has a 10 kA interrupting rating. It's also HACR-rated, making it suitable for certain heating, air-conditioning, and refrigeration applications when equipment specifications call for it. One of the main advantages here is simply space. Instead of using more panel room to accommodate the required circuits, the quadplex layout puts two common-trip, two-pole circuits into a relatively small footprint. That's useful for replacement work and for your compatible load centers where open breaker positions may be limited. As always, don't go by dimensions alone when matching a breaker. Check the panel labeling, breaker type, amperage, voltage, and interrupting rating before installation.

Material Compliance and Certifications

• The Q24020CT2 circuit breaker is HACR-rated and intended for use in compatible electrical distribution equipment. Type QT breakers are designed to meet applicable UL 489 circuit breaker requirements.
• Physical size isn't enough to determine whether a breaker belongs in a particular panel. Before replacing or installing one, check the panel documentation and make sure the breaker type and electrical ratings are approved for that equipment. Installation should also comply with applicable electrical codes and manufacturer requirements.

Where It Works Best

• This breaker is a good fit when you need a 40/20A quadplex configuration and don't have panel space to waste. Its 2-inch width makes it particularly useful in compatible residential or light commercial load centers where several circuits need to be accommodated within the available breaker positions.
