Product FAQs
5 answersWhat type of panels are compatible with the HFJ437150?
This breaker is designed exclusively for legacy Federal Pacific panelboards and switchboards that accept H-Frame, bolt-on molded case circuit breakers. It will not fit standard residential load centers.
Can the HFJ437150 replace older Federal Pacific NFJ series breakers?
Yes, HFJ-frame breakers are commonly used as direct drop-in replacements for older NFJ-frame circuit breakers in existing Federal Pacific enclosures, provided the 150A rating and 3-pole configuration meet your system requirements.
Is the thermal-magnetic trip unit on the HFJ437150 adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) protection functions are factory set and cannot be adjusted in the field.
What hardware is required to mount the HFJ437150 in a Federal Pacific panel?
The breaker features a standard bolt-on connection. Depending on your specific Federal Pacific CDP panelboard, you may need a dedicated mounting hardware kit, such as the NFJ1K, to properly secure the breaker to the busbar. Load-side lugs are included.
Are Federal Pacific HFJ commercial breakers affected by the same issues as residential Stab-Lok breakers?
No, the HFJ series consists of commercial-grade molded case circuit breakers, which utilize a completely different design than the residential FPE Stab-Lok breakers. However, because these are legacy components, regular testing and maintenance are recommended to ensure proper operation.
