Product FAQs
5 answersWhich panelboards are compatible with the QOB360VH circuit breaker?
This bolt-on circuit breaker is specifically designed for use in Square D NQ and NQOD series panelboards. It is not compatible with standard QO residential load centers, which require plug-on circuit breakers.
What does the "VH" signify in the QOB360VH catalog number?
The "VH" suffix indicates a high interrupting rating. Standard QO and QOB breakers typically have a 10kAIC rating, whereas the QOB360VH is rated for 22kAIC at 120/240VAC. This provides enhanced short-circuit protection for demanding commercial and industrial systems.
What is the recommended wire lug torque for the QOB360VH?
The box lugs on the QOB360VH accept 8 to 2 AWG aluminum or copper conductors and should be tightened to 50 lb-in (5.6 N-m). Always verify the manufacturer torque label directly on the circuit breaker before finalizing the installation.
What is the difference between the QO360VH and QOB360VH?
Both circuit breakers share the same 60A rating, 3-pole configuration, and 22kAIC interrupting capacity, but they feature different mounting styles. The QO360VH is a plug-on breaker for standard load centers. The QOB360VH is a bolt-on breaker that uses screws to secure the unit directly to the busbar in commercial NQ and NQOD panelboards.
How does the thermal-magnetic trip unit function on this circuit breaker?
The QOB360VH utilizes fixed long-time and instantaneous (LI) trip functions. The thermal component reacts to sustained overloads by heating a bimetallic strip to break the circuit, while the magnetic component responds immediately to high-level short circuits. It also includes the Visi-Trip visual indicator to help electricians quickly identify a tripped breaker in the panel.
