QC2070 - 70 Amp Circuit Breaker

QC2070 - 70 Amp Circuit Breaker

The QC2070 is a 2-pole, 70-amp thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection in your 120/240VAC electrical distribution systems. Built as a QC (Quicklag) type breaker, it features a 10kA interrupting capacity (A.I.C.) and is HACR rated, making it suitable for a variety of commercial, residential, and light industrial applications where reliable circuit protection is essential. Its cable-in/cable-out configuration helps you to simplify installation in compatible electrical panels, while the thermal magnetic trip mechanism delivers responsive protection against both prolonged overloads and sudden fault currents. Engineered for operation in 40°C ambient environments, the QC2070 is a practical solution for maintaining electrical system safety, minimizing downtime, and helping you protect connected equipment from damage caused by electrical faults.
