Product FAQs
6 answers
What panelboards accept the HQP3050H circuit breaker?
This Quicklag breaker is designed specifically for classic Westinghouse and Eaton Pow-R-Line panelboards that utilize plug-on mounting.
Is the Eaton HQP3050H identical to the legacy Westinghouse version?
Yes. Eaton acquired the Westinghouse electrical distribution line. The current Eaton HQP3050H serves as a direct, exact-fit replacement for legacy Westinghouse breakers sharing the same catalog number.
What wire sizes are compatible with the box lugs on this breaker?
The terminals on the HQP3050H accommodate wire gauges ranging from 14 AWG to 4 AWG. Ensure proper torque specifications are followed during installation.
Can this breaker be used for HVAC applications?
Yes, the HQP3050H is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment circuits.
How does the thermal-magnetic trip unit function on this breaker?
The fixed thermal element provides long-time delay protection against sustained overloads, while the fixed magnetic element delivers instantaneous tripping to clear short circuits safely.
Does the HQP3050H require bolting to the busbar?
No. The HQP series features a plug-on mounting style, allowing it to push directly onto the busbar of compatible Pow-R-Line panelboards without the need for bolted connections.
