Product FAQs
7 answersCan I install the Square D QOU230VH in a standard QO load center?
No. The QOU230VH is a unit-mount circuit breaker designed for OEM panels, control panels, and DIN rail systems. It is not a plug-on breaker and will not fit in standard QO or QOB load centers.
Does the QOU230VH require a separate adapter for DIN rail mounting?
No. The molded case of the QOU230VH includes built-in slots designed to mount directly onto a standard 35mm DIN rail without requiring additional mounting hardware.
Are the line and load connections on the QOU230VH reversible?
Yes. This breaker features field-reversible line and load box lugs, allowing for flexible cable-in and cable-out wiring orientations in control panels and enclosures.
What does the "VH" designate in the QOU230VH catalog number?
The "VH" indicates a very high interrupting rating. While standard QOU breakers are rated at 10 kAIC, the QOU230VH provides a 22 kAIC interrupting rating at 120/240VAC for systems with higher available fault currents.
Is the Square D QOU230VH HACR rated?
Yes. This breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment that requires dedicated overcurrent protection.
Can the QOU230VH replace a standard QOU230 breaker?
Yes. The QOU230VH shares the exact physical dimensions and mounting footprint as the standard QOU230. It can safely replace the standard version in applications where a higher 22 kAIC interrupting rating is required.
Does the QOU230VH feature a tripped circuit indicator?
Yes. It includes a Visi-Trip indicator, which provides a clear visual signal when the breaker has tripped and interrupted the circuit, allowing for quick identification of faults.
