QOB120VH - 20 Amp Circuit Breaker

QOB120VH - 20 Amp Circuit Breaker

The Square D QOB120VH is a 20 amp, 1-pole bolt-on circuit breaker for use in compatible QO panelboards. Rated for 120/240VAC with a 22kA interrupting rating, it provides thermal-magnetic protection for your branch circuits and electrical distribution systems.

This breaker features a Visi-Trip® indicator that shows when the breaker has tripped. The bolt-on mounting design provides a secure installation in the panel, and the trip-free mechanism allows the breaker to open during an overcurrent condition as intended.

The QOB120VH is commonly used in residential, commercial, and light industrial applications where a 20A, 1-pole breaker is required. It is often specified for branch circuits, HVAC equipment, and general distribution systems. Built to last, it provides the proper fit and ratings for compatible QO equipment.
