Product FAQs
8 answersHow is this breaker mounted into a panelboard?
The QOB3100VH is a bolt-on breaker. It fastens directly to the busbar using screw connections, providing a secure installation typically required for commercial and industrial panelboards.
Can I use this QOB breaker in a standard QO load center?
No. QOB breakers feature a bolt-on mounting design intended for NQ and NQOD panelboards. Standard QO load centers require plug-on QO breakers that snap onto the busbar.
What does the "VH" in this catalog number signify?
The "VH" suffix indicates this breaker has a very high interrupting rating of 22 kAIC at 120/240VAC. Standard QO and QOB breakers typically feature a lower 10 kAIC rating.
What conductor sizes and materials are supported by the box lugs?
The terminals on this breaker accept aluminum or copper wire ranging from 4 AWG up to 2/0 AWG. Always refer to the printed label on the breaker face for the precise manufacturer torque specifications before installation.
What happens during an overcurrent condition on just one pole?
This thermal-magnetic breaker features a common trip mechanism. If an overload or short circuit occurs on any single pole, the internal trip-free toggle will cause all three poles to open simultaneously, safely de-energizing the entire circuit.
Is this circuit breaker HACR rated?
Yes, the QOB3100VH is HACR rated. This means it is certified for use with heating, air conditioning, and refrigeration equipment that requires branch-circuit protection bearing this specific designation.
Is there a plug-on equivalent for this circuit breaker?
Yes, if your panelboard or load center requires a plug-on connection rather than a bolt-on connection, the direct equivalent is catalog number QO3100VH.
Which Square D panelboards are rated to accept this breaker?
This 100-amp, 3-pole bolt-on breaker is designed specifically for use in Schneider Electric and Square D NQ and NQOD panelboards.
