Product FAQs
6 answersWhat does the "VH" suffix indicate on the QOU250VH breaker?
The "VH" designates a higher interrupting rating. While standard QOU breakers are rated for 10kAIC, this VH model provides a 22kAIC rating at 120/240VAC.
Are the line and load connections reversible on the QOU250VH?
Yes. QOU circuit breakers are fully tested and UL listed for reverse connection. The box lugs can be wired from either direction without restrictive line or load markings.
How is the QOU250VH mounted in a control panel?
This unit mount breaker can be surface mounted, flush mounted, or snapped directly onto a standard 35mm symmetrical DIN rail.
Does the QOU250VH feature a visual trip indicator?
Yes, it includes the Square D Visi-Trip indicator, which provides a highly visible red flag to quickly identify when the breaker has tripped due to an overload or short circuit.
Is the QOU250VH suitable for heating and cooling equipment?
Yes, this thermal magnetic breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration applications.
Can I use the QOU250VH in a standard QO load center?
No. While it is part of the broader QO family, QOU breakers are unit mount devices designed for OEM panels, control panels, and DIN rail systems, not standard plug-on QO load centers.
