QGA221502 - 150 Amp Circuit Breaker

QGA221502 - 150 Amp Circuit Breaker

If you’re replacing a 150A Q-Frame breaker in an I-Line panelboard, the QGA221502 is built for that exact role. This 2-pole molded case circuit breaker is rated 150 amps with a 65kA interrupting capacity at 240VAC, making it suitable for commercial and industrial distribution systems where available fault current is high. Designed as part of the PowerPact™ Q-Frame family, it installs using a plug-on I-Line connection and provides thermal magnetic protection for dependable overload and short-circuit response.

Contractors and maintenance teams rely on this model when the goal is simple: match the existing specifications and restore proper circuit protection without changing the panel configuration. The molded case housing and internal components are built to last under normal operating conditions, supporting consistent performance in everyday electrical environments.
