Product FAQs
7 answersWhich Square D panels accept the QOM2175VH main breaker?
This breaker fits Square D QO and Homeline load centers that utilize a QOM2 frame. These are typically panels rated between 150A and 225A. It will not fit smaller panels designed for the QOM1 frame.
Can the QOM2175VH be used as a back-fed branch breaker?
No. The QOM2175VH is a dedicated bolt-on main breaker for QOM2 load centers. It cannot be mounted on the standard plug-on bus to back-feed a panel.
Why choose the QOM2175VH over a standard 10kAIC main breaker?
The QOM2175VH provides a 22kAIC interrupting rating at 120/240VAC. This higher rating is often required by local utilities or in areas with higher available fault currents, ensuring safe interruption during severe short circuits.
What type of terminals are provided on the QOM2175VH?
The breaker is equipped with factory-installed box lugs designed to accept 4 AWG to 300 kcmil aluminum or copper conductors, accommodating standard utility service entrance cables.
Can I use the QOM2175VH to upgrade a 150A panel to 175A?
Upgrading a panel's main breaker amperage requires verifying that the load center bus, service entrance conductors, and utility meter housing are all rated for at least 175A. Consult the panel's labeling and local codes before installing a larger main breaker.
How does the Visi-Trip feature work on the QOM2175VH?
When the breaker trips due to an overload or short circuit, the handle moves to a center position and a highly visible red indicator appears in the breaker window. This allows electricians and homeowners to quickly identify the tripped main breaker.
What trip functions are included in the QOM2175VH?
It features standard thermal-magnetic protection with Long-Time (L) and Instantaneous (I) trip functions. The thermal element protects against sustained overloads, while the magnetic element responds immediately to short circuits.
