Information About QO120VH
The QO120VH is part of the Square D QO series of miniature circuit breakers known for their compact construction and high fault-current performance. It is built with a molded case housing and a trip-free, over-center toggle mechanism that ensures consistent operation under fault conditions. The breaker integrates directly into QO load centers using a plug-in mounting interface and pressure plate terminals for secure conductor connections. It is commonly used in residential, commercial, and light industrial panels where high interrupt ratings, visual trip indication, and thermal-magnetic protection are required.
Key Features:
- QO series design: Compatible with Square D QO load centers.
- Thermal-magnetic trip unit: Provides protection against overloads and short circuits.
- High interrupt rating: Rated 22kA at 120/240V AC.
- Single-pole configuration: Protects one branch circuit.
- Plug-in mounting: Allows fast installation and replacement.
- VisiTrip indicator: Visual confirmation when the breaker has tripped.
- HACR and switching duty rated: Suitable for HVAC and general switching applications.
The QO120VH delivers the reliability and precision required for branch circuit protection in load center distribution systems.
