Product FAQs
7 answersWhich panelboards accept the Federal Pacific HF631020 circuit breaker?
This legacy molded case circuit breaker is engineered to bolt directly into existing Federal Pacific F-Frame panelboards, allowing you to maintain aging infrastructure without retrofitting.
Does the HF631020 fit into H-Frame or F-Frame panelboards?
While this breaker belongs to the Federal Pacific H-Frame family, it is specifically designed and rated for use within legacy Federal Pacific F-Frame panelboards.
What wire gauge range is supported by the terminals on this 20A breaker?
The factory-installed load side lugs accept wire sizes from 14 AWG up to 1/0 AWG, providing flexibility for various field wiring requirements.
Can the trip curve be adjusted on the HF631020?
No. This breaker features fixed thermal and fixed magnetic trip elements, providing standard long-time and instantaneous (LI) protection without field adjustability.
Is the Federal Pacific HF631020 a current production model?
No. Federal Pacific Electric (FPE) is no longer manufacturing new equipment. This breaker serves as a direct drop-in replacement for maintaining existing legacy FPE systems.
Does this breaker require a mounting kit or adapter for installation?
No aftermarket adapters are required. The HF631020 features a standard bolt-on connection designed to mount securely to the original Federal Pacific busbar.
How does the thermal magnetic trip unit function on this breaker?
The thermal element protects against sustained overloads by heating up and tripping the breaker, while the magnetic element provides immediate response to clear instantaneous short circuits.
