QGA221251 - 125 Amp Circuit Breaker

QGA221251 - 125 Amp Circuit Breaker

The Square D QGA221251 is a 125 amp, 2-pole circuit breaker designed for your commercial and industrial electrical distribution systems. Rated for 240VAC, this PowerPacT Q breaker uses thermal-magnetic protection to help protect your circuits from overloads and short circuits. With a 65kA interrupting rating at both 120/208VAC and 240VAC, it’s commonly used in systems where higher fault current capacity is required.

This breaker is built with I-Line connections on the line side and mechanical lugs on the load side for use in compatible panelboards.
