QC40 - 40Amp Circuit Breaker Description

QC40 - 40Amp Circuit Breaker

Keep your existing electrical distribution system operating with the QC40 40 Amp 2-Pole Plug-On Thermal-Magnetic Circuit Breaker, a replacement circuit breaker compatible with legacy QC load centers. This 40-amp, 2-pole plug-on circuit breaker provides thermal-magnetic overcurrent protection for 120/240 VAC electrical systems and features a 10 kA interrupting capacity (A.I.C.). Built for dependable, long-term service, it is engineered for proper form, fit, and function, allowing it to install in the existing QC40 breaker location without requiring panel modifications. As the original QC40 is no longer manufactured, this new aftermarket replacement is specially designed to fit and replace the original breaker while maintaining the electrical ratings and physical compatibility required for the application.
