QC-40 - Thomas & Betts 40 Amp 120/240V 2 Pole Circuit Breaker

QC-40

QC-40 is a 2-pole, 40 amp circuit breaker designed for 120/240V AC applications, providing reliable protection for residential and light commercial branch circuits. This Thomas & Betts breaker features a thermal-magnetic trip unit for fast short-circuit and time-delay overload protection. The side-clip design allows for common-trip operation in a compact 1-inch mounting space, ensuring safe and efficient installation. Each unit is factory calibrated and tested for consistent performance. Engineered for durability, the QC-40 breaker includes a quick-make, quick-break trip-free mechanism that prevents forced operation during faults. The breaker's arc chutes and exhaust vents safely manage arc interruption and minimize ionized gases. Movable contact wiping action helps maintain clean contact surfaces for long-term reliability.
