Product FAQs
6 answersWhat panelboards are compatible with the QOB115-1022 circuit breaker?
This breaker is designed for Square D NQ and NQOD panelboards. Because it utilizes a bolt-on connection, it cannot be installed in standard QO load centers, which require plug-on breakers.
What does the -1022 suffix indicate on the QOB115-1022 catalog number?
The -1022 suffix designates that the breaker includes a factory-installed shunt trip accessory. This allows the breaker to be opened remotely when a control voltage signal is applied to the shunt trip coil.
Can the QOB115-1022 be applied in DC voltage systems?
Yes, this breaker is dual-rated for both AC and DC applications. It carries a 10kAIC interrupting rating at 120/240VAC and a 5kAIC interrupting rating at 48VDC.
What are the wire size requirements for the QOB115-1022 terminals?
The pressure plate terminals accept 14 AWG to 8 AWG aluminum or copper conductors. Always verify the specific torque requirements printed on the breaker label during installation.
How does the thermal-magnetic trip mechanism operate on this breaker?
The breaker features fixed long-time and instantaneous (LI) trip functions. The thermal element provides delayed tripping for sustained overloads, while the magnetic element trips instantaneously to clear short-circuit faults.
How is the QOB115-1022 secured within the panelboard?
It uses a bolt-on mounting style that fastens directly to the panelboard busbar with a mounting screw. This provides a highly secure, vibration-resistant mechanical and electrical connection compared to plug-on designs.

Great price. Fast delivery. My local electric distributor wanted double for the same breaker, so it was a no brainer to order this one. Ordered another one since with the same great service.
