Product FAQs
6 answersHow does the QOU115VH mount inside an enclosure or panel?
The QOU115VH is a unit-mount breaker that features built-in slots for standard 35mm DIN rail mounting. It can also be surface-mounted or flush-mounted using field-installable mounting brackets.
What does the VH designate in the QOU115VH catalog number?
The VH indicates a higher interrupting rating. While standard QOU breakers are rated for 10 kAIC, the QOU115VH provides a 22 kAIC interrupting capacity at 120/240VAC for systems with higher available fault currents.
Are the line and load connections on the QOU115VH reversible?
Yes, QOU circuit breakers feature reversible line and load box lugs. This feed-thru design allows you to wire the supply power to either the top or bottom terminal for flexible installation in OEM panels and enclosures.
Does the QOU115VH include a tripped status indicator?
Yes, this breaker features the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, the handle moves to a center position and a highly visible red indicator appears to help quickly identify the faulted circuit.
Is the QOU115VH suitable for use with heating and air conditioning equipment?
Yes, this breaker is HACR rated, meaning it is approved for group installation and can safely protect the motor loads found in heating, air conditioning, and refrigeration equipment.
What size wire is compatible with the box lugs on the QOU115VH?
The slotted box lugs on this 15-amp breaker accept a single copper or aluminum wire ranging from 14 AWG to 2 AWG.
