Q21515CT - Quadplex 15/15 Circuit Breaker

Q21515CT - Quadplex 15/15 Circuit Breaker

When panel space is tight, the Q21515CT 15 Amp Type QT circuit breaker offers a compact way to provide circuit protection without taking up more room than necessary. This plug-in breaker features a quadplex configuration, a 15-amp rating, and a 10 kAIC rating at 120/240 VAC. It also includes common-trip operation and is HACR rated, making it suitable for applicable heating, air-conditioning, and refrigeration circuits. Measuring just 3.13 inches high, 2 inches wide, and 2.56 inches deep, the Q21515CT is a practical option for replacement work, panel maintenance, and other applications where this exact Type QT breaker and its electrical ratings are required. If you're replacing an existing breaker, matching the part number is a good starting point, but don't stop there—check the panel labeling and electrical specifications to make sure the breaker is approved for the application.

Key Features and Benefits

• 15-amp rating for compatible branch-circuit applications.
• 10 kA IC at 120/240 VAC provides the specified fault-current interrupting capacity.
