QOB130 30 A Single-Pole Breaker
The Square D QOB130 is a bolt-on miniature circuit breaker rated at 30 amps for 120/240 V AC and 48 V DC systems. It carries a 10 kA interrupting rating at 120/240 V AC and fits QO and NQOD panelboards with a pressure-plate terminal connection.
QO panelboard upgrades and new installs
This breaker suits electricians adding or replacing a single-pole circuit in Square D QO or NQOD load centres. It will not suit panels that accept only plug-on breakers, nor three-phase or multi-pole applications requiring common-trip operation.
10 kA AIR at 120/240 V AC
The 10 kA interrupting rating is the critical figure that determines whether this device can safely clear a fault in the target installation. Verify that the available fault current at the panel does not exceed this value before specifying the breaker.

Questions about this item
What load-center series must I already have to install this QOB130 breaker?
It fits Square D NQOD panelboards and QO-series load centers only.
Will the 10 kA interrupting rating coordinate with older QO breakers already in the panel?
Yes, the 10 kA AIR at 120/240 V AC matches the standard rating used on legacy QO devices.
How can I verify the breaker is seated correctly after bolting it on?
The paddle actuator should snap firmly into the ON position and the pressure-plate terminals must grip the conductors tightly.
