Product FAQs
5 answersWhat panels are compatible with the HFJ437200?
This breaker is specifically designed for legacy Federal Pacific panels and switchgear configured for H-frame or HFJ-7 frame molded case circuit breakers.
What wire sizes do the lugs on the HFJ437200 accept?
The factory lugs accommodate wire sizes from 4 AWG up to 350 kcmil. Ensure your conductors fall within this range and are torqued to the manufacturer specifications during installation.
Are the trip settings on the HFJ437200 adjustable?
No. This breaker utilizes a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection but does not offer field-adjustable trip dials.
Is the Federal Pacific HFJ437200 still in active production?
Federal Pacific Electric is no longer in business, making this a legacy component. It is sourced specifically to maintain existing FPE switchgear and is not intended for new electrical system designs.
Does this breaker plug into the busbar?
No, the HFJ437200 features a bolt-on connection. It must be securely bolted directly to the busbar in compatible Federal Pacific enclosures.
