SQUARE D QOU160 60A 1 Pole 120/240V AC Circuit Breaker

QOU Series 60A Miniature Breaker

This Square D QOU160 is a single-pole miniature circuit breaker rated at 60 amps for 120/240V AC systems. It also carries a 48V DC rating and a 10kA interrupting rating at the AC voltage. The device uses a toggle actuator and mounts on a surface or DIN rail within compatible QO panelboards or load centers. The 100A frame size and slotted box lug terminals accept reversible line and load connections.

Suits QO panelboards needing single-pole protection

Electricians and facility managers maintaining Square D QO load centers will find this breaker a direct fit for 60A branch circuits. It is listed for air conditioning, refrigeration and heating equipment. Buyers who need multi-pole protection, a different amperage, or a breaker for a non-QO panel series should look at other models. The single-pole design does not serve 240V-only loads that require two poles.

Sustained load performance in QO enclosures

Under continuous operation the breaker runs at its 60A rating within the thermal limits of the QO panelboard environment. The 10kA AIR rating means it can interrupt heavy fault currents without damage when installed in a properly rated enclosure. The toggle mechanism provides a clear visual indication of tripped status after an overload or short-circuit event. Heat dissipation depends on the surrounding panelboard ventilation and ambient temperature.
