Square D QO325 circuit breaker 25 A 3 pole
This Square D QO325 miniature circuit breaker provides 25 A overcurrent protection across three poles at 120/240 V AC. It is built for QO load centres and NQ panelboards with a plug-in mounting style and a 10 kA interrupting rating.
Suits three-phase 25 A branch circuits.
Electricians wiring 25 A three-phase branch circuits in compatible QO or NQ equipment will find this breaker a direct fit. Installations that require a larger frame size, a different interrupting rating, or a non-QO panelboard should select another device.
10 kA interrupting rating at 120/240 V AC
The breaker carries a maximum AIR rating of 10 kA at 120/240 V AC, which determines whether it can safely clear a fault on the intended circuit. Verify that the available fault current at the installation point does not exceed this value before specifying the device.
