Square D QO130 Miniature Circuit Breaker

No. Despite both being manufactured by Square D, QO and Homeline circuit breakers have entirely different form factors and bus bar mounting mechanisms. This breaker will only fit QO load centers, NQ panelboards, and Speed-D switchboards.

The QO130 features a plug-on mounting style, while the QOB130 is a bolt-on breaker. Although they share the same internal trip mechanisms and electrical ratings, bolt-on breakers are required in certain commercial panelboards and cannot be used in standard plug-on load centers.

You can only replace a QO130VH with a standard QO130 if the system's available fault current is verified to be 10,000 amps or less. The VH version has a 22kAIC rating compared to the 10kAIC of this standard breaker. Downgrading the interrupting capacity in a panel that requires 22kAIC is a severe safety hazard.

Visi-Trip is a signature Square D safety and diagnostic feature. When the breaker trips due to an overcurrent or short circuit, the handle snaps to a center position and a bright red indicator appears in a viewing window. This allows you to rapidly identify the tripped circuit in a dark or crowded panel.

Yes. While commonly used for 120/240VAC single-phase branch circuits, this model is also UL listed for DC power systems up to 48VDC. When used in a DC application, the maximum interrupting rating is 5kA.

Yes, it is HACR rated. This means it has been tested and certified to safely handle the initial inrush currents typical of Heating, Air Conditioning, and Refrigeration motor loads without nuisance tripping.
