Product FAQs
7 answersCan I install the QOU315VH in a standard Square D QO load center?
No. QOU circuit breakers are unit-mount devices designed for OEM panels, control panels, and DIN rail systems. They do not have the plug-on configuration required to fit into QO load centers.
How is the QOU315VH mounted in an enclosure?
This breaker is a unit-mount type that can be surface-mounted, flush-mounted, or snapped directly onto a standard 35mm DIN rail.
Are the line and load connections on the QOU315VH reversible?
Yes. QOU breakers feature reversible line and load box lugs, allowing you to feed the breaker from either direction without affecting its protective functions.
What does the VH stand for in the QOU315VH catalog number?
The VH indicates a very high interrupting rating. While standard QOU breakers are rated for 10 kAIC, the QOU315VH is rated for 22 kAIC at 240VAC.
Can the QOU315VH be used in DC electrical systems?
Yes. In addition to its AC ratings, this thermal-magnetic breaker is UL Listed for use in DC applications up to 48VDC with a 5 kAIC interrupting rating.
Are field-installable shunt trips available for the QOU315VH?
No. Electrical accessories like shunt trips and auxiliary switches for QOU breakers must be factory-installed and will take up an additional pole space in your panel.
Does the QOU315VH feature a visual trip indicator?
Yes, this breaker includes Square D Visi-Trip technology. When the breaker trips due to an overcurrent or short circuit, a highly visible red indicator appears to help you quickly identify the tripped circuit.
