Product FAQs

6 answers
Which panelboards accept the HQP3030H circuit breaker?

This Quicklag plug-on breaker is specifically designed to install into Eaton and legacy Westinghouse Pow-R-Line panelboards.

Can I use an Eaton HQP3030H to replace an older Westinghouse HQP3030H?

Yes. Eaton acquired the Westinghouse electrical distribution line. An Eaton-branded HQP3030H is the direct, manufacturer-approved replacement for older Westinghouse or Cutler-Hammer models sharing the same catalog number.

Is the Eaton HQP3030H suitable for HVAC equipment?

Yes, this breaker is HACR rated, meaning it is certified for safe use with heating, air conditioning, and refrigeration equipment circuits.

How does the thermal-magnetic trip mechanism work on the HQP3030H?

The fixed thermal-magnetic trip unit provides dual protection. The thermal component offers long-time protection against gradual overloads, while the magnetic component delivers instantaneous protection against short circuits.

Does the HQP3030H feature a common trip mechanism?

Yes. As a 3-pole breaker, it utilizes an internal common trip. If a fault is detected on any single pole, all three poles will trip simultaneously to safely disconnect the 3-phase load.

What wire sizes are compatible with the HQP3030H terminals?

The box lugs accept wire gauges from 14 AWG up to 4 AWG. Always verify that your selected conductor size meets local electrical codes for a 30-amp circuit.
