Product FAQs

6 answers
What is the difference between the Square D QOU225 and the QOUR225?

The QOUR225 is identical to the standard QOU225 miniature circuit breaker, but it features field-reversible lugs that are reversed by the factory prior to shipment. This allows for easier flush mounting and back-wiring in OEM and control panels.

How is the QOUR225 circuit breaker mounted?

This unit-mount breaker can be installed directly onto a standard 35mm DIN rail, surface-mounted, or flush-mounted, making it highly adaptable for custom enclosures and control panels.

Can the QOUR225 be used in DC power applications?

Yes, in addition to its 120/240VAC rating, this 2-pole breaker is rated for use in DC circuits up to 48VDC, where it provides an interrupting capacity of 5kA.

Does this breaker include a visual trip indicator?

Yes, the QOUR225 features the Square D Visi-Trip visual indicator, which provides a clear visual cue to quickly identify when the breaker has tripped during a fault.

What type of wire can be used with the QOUR225 box lugs?

The factory-reversed box lugs accept either aluminum or copper conductors ranging from 14 AWG to 2 AWG.

What type of protection does the QOUR225 provide?

It utilizes a fixed thermal-magnetic trip mechanism to deliver both long-time overcurrent protection and instantaneous short-circuit protection for commercial and industrial applications.
