Product FAQs
5 answersWhat panelboards are compatible with the HM632500 circuit breaker?
The HM632500 is a legacy H-Frame breaker designed specifically for bolt-on installation in older Federal Pacific Electric (FPE) switchgear and panelboards.
How are the line and load connections made on the HM632500?
The line side of the breaker bolts directly to the panelboard bus, while the load side is equipped with mechanical lug terminals for terminating the outgoing conductors.
Are the trip settings on the HM632500 adjustable?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection at 500 amps, combined with an adjustable magnetic element for instantaneous short-circuit protection.
What does the LI trip function code mean for this breaker?
The LI code indicates that the breaker provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against short circuits, utilizing a thermal-magnetic trip mechanism.
Is the HM632500 a direct replacement for older Federal Pacific 500A breakers?
Yes, it serves as a direct bolt-on replacement for legacy 500-amp, 3-pole Federal Pacific H-Frame breakers with matching interrupting ratings in existing FPE enclosures.
