QOM2175VH - 175 Amp Circuit Breaker

QOM2175VH - 175 Amp Circuit Breaker

The Square D QOM2175VH is a 175 amp, 2-pole main breaker made for QO and Homeline load centers. Rated for 120/240VAC with a 22kA interrupting capacity, it serves as the primary disconnect and overcurrent protection device in residential, commercial, and light industrial panels.

This breaker is designed with a thermal-magnetic trip mechanism and includes a Visi-Trip® indicator that lets you quickly see if the breaker has tripped. The bolt-on design keeps it secure in the panel while providing reliable operation over time. Whether you’re replacing an existing main breaker or installing a new panel, the QOM2175VH fits directly into compatible QO or Homeline systems and provides the proper ratings for branch circuits, HVAC equipment, and general power distribution.
