60 A Bolt-On Breaker for QO Panels

The Square D QOB260 is a two-pole miniature circuit breaker rated at 60 amps for 120/240 V AC and 48 V DC systems. It mounts with a bolt-on connection and uses a paddle actuator for manual switching. The unit carries a 10 kA interrupting rating at 120/240 V AC and fits within a 100 A QO frame.

Ideal for Standard QO Load Centres

Suited for electricians and facility managers adding or replacing branch protection in Square D NQOD panelboards where a standard 60 A two-pole breaker is required. Not a fit for panels that accept only plug-on breakers, for applications needing a higher interrupting rating, or for three-phase loads that demand a three-pole device.

Fits QO Series Enclosures

The breaker installs directly into compatible QO load centres using the bolt-on mounting style and lug terminals. Its 3.1 in length, 1.5 in width and 2.9 in depth allow it to occupy a standard two-pole slot without special spacing. Operating temperature minimum is 77 degrees F, so the enclosure must remain above that threshold.

Questions about this item

Does this QOB260 breaker require a Square D QO series panelboard to install?

Yes, it is designed for Square D QO and NQOD panelboards and uses a bolt-on mounting style.

Will the 10 kA interrupting rating at 120/240 V AC protect older branch circuits in the same panel?

The 10 kA AIR rating applies to the breaker itself; existing circuits remain protected by their own devices.

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

Confirm the paddle actuator moves firmly to the ON position and the circuit carries load without nuisance tripping.
