QDA220701 - 70 Amp Circuit Breaker

QDA220701 - 70 Amp Circuit Breaker

The QDA220701 is a 70 amp, 2-pole molded case circuit breaker built for reliable protection in 240VAC distribution systems. Designed as part of the PowerPact Q-Frame family, this breaker features a thermal magnetic trip unit that responds to both overloads and short circuits—helping prevent damage to wiring and connected equipment. With a 25kA interrupting rating at 240VAC, it’s capable of handling higher fault levels commonly found in commercial and light industrial applications. This model is configured as an I-Line, plug-on breaker for A-B phase connections, making it a practical choice for compatible panelboards and switchboards. The QDA frame design supports consistent performance under normal operating conditions while offering the protection professionals expect from a molded case breaker. At 70 amps, it’s commonly used for feeder circuits, HVAC loads, lighting panels, and other equipment that requires dependable 240V protection.
