Product FAQs

8 answers
What does the 1021 suffix mean on the QOB225VH1021 catalog number?

The 1021 suffix indicates that this circuit breaker includes a factory-installed shunt trip accessory. This allows the breaker to be opened remotely using a 120, 208, or 240 VAC control signal, which is commonly required for emergency shutdown or fire alarm systems.

What panelboards are compatible with the QOB225VH1021?

This bolt-on miniature circuit breaker is designed for use in Square D NQ and NQOD panelboards. It is not compatible with standard QO load centers, which require plug-on breakers.

What does the VH designate in the QOB225VH1021 catalog number?

The VH indicates a high interrupting rating. This breaker is rated for 22,000 Amps Interrupting Capacity (22 kAIC) at 120/240 VAC, which is higher than the 10 kAIC rating found on standard QOB breakers.

What wire sizes and materials are accepted by the terminals on this breaker?

The pressure plate terminals on the QOB225VH1021 accept 14 AWG to 8 AWG wire. The terminals are rated for use with both copper and aluminum conductors.

Can I install the QOB225VH1021 in a standard residential QO load center?

No. The QOB series features a bolt-on connection designed specifically for commercial and industrial NQ and NQOD panelboards. Standard residential QO load centers require plug-on breakers.

How is the QOB225VH1021 secured to the panelboard bus?

This breaker uses a bolt-on connection. It fastens directly to the bus bars of NQ or NQOD panelboards using screws, providing a secure, vibration-resistant connection suitable for commercial and industrial environments.

How does the thermal-magnetic trip mechanism operate in this breaker?

The thermal-magnetic trip unit provides two types of protection. The thermal component protects against sustained overloads, while the magnetic component trips the breaker immediately in the event of a severe short circuit.

Does this breaker include a Visi-Trip indicator?

Yes. Like most Square D QO and QOB breakers, it features a Visi-Trip indicator. When the breaker trips, a highly visible red indicator appears in the window, making it easy to identify the tripped circuit in a crowded panelboard.
