Product FAQs
5 answersWhich panelboards accept the QOB1351021 circuit breaker?
This bolt-on QOB breaker is designed exclusively for Square D NQ and NQOD panelboards. It cannot be installed in standard QO load centers, which require plug-on style breakers.
What does the 1021 suffix indicate on this part number?
The 1021 suffix designates a factory-installed 120/240VAC shunt trip accessory. This allows the breaker to be tripped remotely via an external control voltage.
How is the shunt trip accessory on the QOB1351021 operated?
The shunt trip requires a momentary application of 120V or 240V AC to its control coil. Once energized by an external switch or relay, the coil mechanically opens the breaker contacts.
Does this breaker include the Square D Visi-Trip indicator?
Yes, it features the standard Visi-Trip mechanism. When the breaker trips due to an overcurrent or shunt trip activation, the handle snaps to a center position and a red indicator appears in the window for quick identification.
Is the QOB1351021 suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is certified for use with multi-motor and combination loads typical in heating, air conditioning, and refrigeration systems.
