QDA221502 - 150 Amp Circuit Breaker

QDA221502 - 150 Amp Circuit Breaker

The QDA221502 is a 150 amp, 2-pole molded case circuit breaker built for dependable protection in 240VAC electrical distribution systems. Designed as part of the PowerPact™ Q-Frame family, this breaker uses a thermal magnetic trip mechanism to respond to both overloads and short circuits. With a 25kA interrupting rating at 240VAC, it is suited for commercial and light industrial applications where equipment protection and code-compliant performance matter. The I-Line, plug-on configuration allows for straightforward installation in compatible panelboards and switchboards, making it a practical solution for replacements, retrofits, or system expansions.

Instead of overcomplicating things, this breaker does exactly what it’s supposed to do: protect circuits, minimize damage during faults, and help maintain system stability. Its molded case construction and proven trip technology make it a dependable choice for protecting feeders and branch circuits in everyday working environments.
