Product FAQs

5 answers
What type of panelboards accept the QOB130 breaker?

It installs in Square D NQ and NQOD panelboards. The bolt-on connection secures the breaker directly to the panel busbar for reliable performance in commercial and industrial electrical systems.

Can I substitute the QO130 for the QOB130?

No, these breakers are not interchangeable. The QO130 is a plug-on model designed for QO load centers. The QOB130 uses a bolt-on mounting mechanism required for NQ and NQOD series panelboards.

How much physical panel space does the QOB130 require?

As a standard single pole miniature breaker, it occupies one 0.75-inch space on the panelboard busbar.

Is this 30-amp breaker approved for HVAC equipment?

Yes, it is HACR rated. This means it is certified for use with the specific motor group combinations commonly found in heating, air conditioning, and refrigeration equipment.

How does the trip indicator work on this circuit breaker?

This model features Visi-Trip technology. When an overcurrent or short circuit causes the breaker to trip, a bright red flag appears in the indicator window, allowing electricians to quickly locate the tripped circuit in a crowded panel.
