Product FAQs
8 answersWhich panelboards are compatible with the QOB2201201 circuit breaker?
This bolt-on miniature circuit breaker is designed exclusively for use in Square D NQ and NQOD panelboards. It will not fit in standard QO load centers, which require plug-on breakers.
What does the 1201 suffix indicate on the QOB2201201 catalog number?
The 1201 suffix means this breaker includes a factory-installed 1B auxiliary switch. This provides a normally closed contact used to monitor the open or closed status of the breaker for remote signaling.
What wire sizes are accepted by the terminals on the QOB2201201?
The pressure plate terminals on this breaker accept aluminum or copper conductors ranging from 14 AWG to 8 AWG. Ensure proper torque is applied during installation as specified on the breaker label.
Can the QOB2201201 be used in DC electrical systems?
Yes, in addition to its standard AC ratings, this thermal-magnetic breaker is rated for 48VDC applications with an interrupting capacity of 5kAIC.
How does the QOB2201201 mount into the panelboard?
It features a bolt-on connection type, requiring it to be physically bolted to the bus bar of an NQ or NQOD panelboard. This provides a secure, vibration-resistant connection compared to standard plug-on designs.
Does the QOB2201201 feature a tripped circuit indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips due to an overload or short circuit, a highly visible red indicator appears in the window to help quickly identify the faulted circuit.
What type of protection does the LI trip function provide?
The LI designation stands for Long-Time and Instantaneous trip functions. The thermal component provides long-time protection against gradual overloads, while the magnetic component provides instantaneous protection against severe short circuits.
Is the QOB2201201 HACR rated for HVAC equipment?
Yes, standard QO and QOB circuit breakers are UL Listed as HACR type, making them suitable for group motor applications found in heating, air conditioning, and refrigeration equipment.
