Q24030CT - Quadplex 40/30 Circuit Breaker

Q24030CT - Quadplex 40/30 Circuit Breaker

The Q24030CT 40/30 Amp Type QT circuit breaker is a compact quadplex breaker made for compatible panels that accept Type QT plug-in breakers. If you're replacing an existing Q24030CT, the first things you'll probably want to check are the ratings: 40/30 amps, 120/240 VAC, and 10 kA I.C. This breaker also features a common-trip design and is HACR-rated. One of its biggest advantages is its size. The quadplex configuration provides multiple circuit-protection functions while making efficient use of limited panel space. The breaker measures 3.13 inches high, 2 inches wide, and 2.56 inches deep, so it's easy to compare the physical dimensions with your existing equipment. Whether you're handling a replacement, repair, or routine electrical maintenance job, the Q24030CT offers a straightforward solution when these exact specifications are required. As with any circuit breaker, be sure to check panel compatibility and all electrical ratings before installation.

Material Compliance and Certifications

• The Q24030CT is HACR-rated and has a 40°C rating according to the available product specifications. No additional material-compliance certifications have been provided, so they should not be assumed.
• When matching a breaker to an existing installation, check more than just the amp rating. The breaker type, voltage, interrupting rating, trip configuration, physical size, and compatibility with the electrical panel all matter.

Where It Works Best

• The Q24030CT is best suited to compatible electrical panels that accept Type QT plug-in circuit breakers. Its quadplex layout is particularly useful when panel space is tight and the application calls for the specific 40/30-amp configuration.
• It's also a practical choice for replacement and maintenance work when you're matching an existing Q24030CT. Check the part number on the breaker you're replacing, then compare the amperage, voltage, A.I.C. rating, breaker type, and dimensions. A matching part number is helpful, but the complete electrical requirements should always be verified before installation.
