Built to manage elevated fault currents, this high-interrupting 70-amp breaker serves demanding commercial and residential electrical systems. The device mounts into standard QO load centers and NQ/NQOD panelboards, requiring two pole spaces. With a robust 22kAIC capacity at 120/240V, it offers enhanced safety margins over standard models. A built-in Visi-Trip red indicator simplifies maintenance by clearly flagging tripped conditions across the panel.Specifications

Product FAQs
7 answersCan I install the QO270VH in a Square D Homeline panel?
No. QO and Homeline circuit breakers are not interchangeable. The QO270VH has a 3/4-inch format and is only compatible with QO load centers, NQ panelboards, and NQOD panelboards.
How many panel spaces does the QO270VH require?
This 2-pole breaker requires two standard 3/4-inch spaces in a compatible QO load center or NQ/NQOD panelboard.
What does the VH suffix mean in the QO270VH catalog number?
The VH indicates a high interrupting rating of 22,000 Amps (22kAIC) at 120/240VAC. This provides higher fault protection compared to the 10kAIC rating found on standard QO breakers.
Is the QO270VH suitable for use with heating and air conditioning equipment?
Yes. This breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires a 70A overcurrent protection device.
What is the recommended tightening torque for the box lugs on the QO270VH?
The manufacturer specifies a tightening torque of 44.25 lb-in (5 N.m) for the 8-2 AWG aluminum or copper conductors.
Does the QO270VH feature a tripped circuit indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips, a highly visible red indicator appears in the window to help you quickly identify the tripped circuit.
Is there a bolt-on equivalent available for the QO270VH?
Yes. If your NQ or NQOD panelboard requires a bolt-on connection rather than a plug-on connection, the equivalent breaker is the QOB270VH.
