QO Series 25 A Single-Pole Breaker

This Square D QOU125 miniature circuit breaker carries a 25 A rating and a 120/240 V AC voltage rating with a 10 kA interrupting capacity. It fits QO-series panelboards and load centres using a surface or DIN-rail mounting style. The toggle actuator provides clear on-off indication for single-phase circuits.

Suits standard 25 A branch circuits

It serves air-conditioning, refrigeration and heating equipment on a 25 A single-pole branch. Installations that require a two-pole breaker, a higher ampere rating, or a different panelboard series should select another device. The reversible slotted box lug accepts line or load conductors in either orientation.

10 kA AIR at 120/240 V AC

The 10 kA maximum ampere interrupting rating at 120/240 V AC determines whether the breaker can safely clear a fault on the supply side. Verify that the available fault current at the installation point does not exceed this value before specifying the QOU125.

Questions about this item

Can the QOU125 breaker share a QO load center with other single-pole QO breakers?

Yes, it is a 1-pole standard QO-series breaker rated 25 A at 120/240 V AC and mounts on the same DIN-rail or surface bus as other QO units.

How do I verify the breaker is operating correctly after installation?

Switch the toggle to ON; the handle should stay firmly latched. Measure 120 V or 240 V AC across the load terminal with a multimeter to confirm continuity.

What comes in the box and what must I supply?

The breaker itself with its slotted reversible box lug terminals is included; mounting rail, panel enclosure, and wire are not supplied.
