Product FAQs
6 answersWhat does the 1021 suffix mean on the QOB360VH1021 circuit breaker?
The 1021 suffix indicates that this breaker includes a factory-installed shunt trip accessory rated for 120, 208, or 240VAC. This allows the breaker to be opened remotely via an external control signal.
Which panelboards are compatible with this 60A bolt-on breaker?
The QOB360VH1021 is designed specifically for installation in Square D NQ and NQOD series panelboards.
What does the VH designation indicate in the part number?
The VH indicates that this is a high-interrupting capacity breaker. It provides a 22kAIC rating at 120/240VAC, which is higher than the 10kAIC rating found on standard QOB breakers.
What wire sizes are accepted by the terminals on the QOB360VH1021?
The box lug terminals on this breaker accept wire gauges from 8 AWG to 2 AWG. The terminals are rated for use with both aluminum and copper conductors.
How does a QOB breaker differ from a standard QO breaker during installation?
QOB breakers utilize a bolt-on connection to secure directly to the panelboard bus, which is typical in commercial and industrial settings. Standard QO breakers use a plug-on mounting style.
How can I tell if the QOB360VH1021 has tripped?
This breaker features the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or a shunt trip activation, a highly visible red indicator appears in a window on the face of the breaker.
