Product FAQs
6 answersWhat does the 1021 suffix indicate on the QOB380VH1021?
The 1021 suffix indicates that this breaker includes a factory-installed 120/208/240VAC shunt trip accessory. This allows the breaker to be tripped remotely via a control signal for emergency shutdowns or automated control.
How many panel spaces does this breaker require?
The QOB380VH1021 requires 4 panel spaces total. The 3-pole breaker occupies three spaces, and the factory-installed shunt trip accessory requires one additional space.
Which panelboards are compatible with this bolt-on breaker?
This breaker is designed specifically for bolt-on installation in Square D NQ and NQOD panelboards. It cannot be used in standard QO load centers, which require plug-on breakers.
What does the VH designation mean in the catalog number?
The VH indicates that this is a very high interrupting capacity breaker. It provides a 22kAIC rating at 120/240VAC, which is higher than the standard 10kAIC rating found on base QOB breakers.
Is this circuit breaker HACR rated?
Yes, this breaker is HACR rated, making it suitable and approved for use with heating, air conditioning, and refrigeration equipment.
Does this breaker include a tripped circuit indicator?
Yes, it features the Square D Visi-Trip visual indicator. When the breaker trips, a highly visible red flag appears in the window, making it easy to identify the tripped circuit in a panelboard.
