QBA220701 - 70 Amp Circuit Breaker

QBA220701 - 70 Amp Circuit Breaker

The QBA220701 is a 70 amp, 2-pole molded case circuit breaker designed for use in 240VAC distribution systems. Built on the PowerPact Q-Frame, this breaker features a thermal magnetic trip unit, which means it reacts to both sustained overloads and sudden short circuits. It’s configured as an I-Line, plug-on breaker, allowing it to connect directly into compatible I-Line panelboards without additional mounting hardware.

With a 10kA interrupting rating at 240VAC, this breaker is suitable for many commercial and light industrial electrical systems. It’s commonly used when replacing an existing QBA frame breaker or when expanding capacity within a properly rated panelboard. The molded case design helps enclose and protect internal components while supporting safe operation under normal service conditions.

Key Features and Benefits
