Product FAQs
4 answersWhat enclosures are compatible with the HFJ631200 circuit breaker?
This legacy H-frame breaker is specifically designed for use in older Federal Pacific (FPE) panelboards and switchboards that accept 3-pole, bolt-on molded case circuit breakers.
What are the wire size requirements for the HFJ631200 lugs?
The standard load-side lugs on this breaker are rated to accept conductors ranging from 4 AWG up to 350 kcmil. Proper torque must be applied during installation to ensure a secure connection for 200-amp loads.
How does the thermal-magnetic trip unit function on the HFJ631200?
The breaker uses a fixed thermal element for long-time overload protection and a fixed magnetic element for instantaneous short-circuit protection. These LI functions are non-adjustable and factory set for 200-amp commercial applications.
Does the HFJ631200 share the safety concerns associated with Federal Pacific Stab-Lok breakers?
No. The HFJ series is a commercial-grade, bolt-on molded case circuit breaker. It does not use the residential Stab-Lok plug-on design, which is the primary source of safety and reliability issues in legacy Federal Pacific load centers.
