Product FAQs
6 answersWhat panels or switchgear will accept the HM632000 circuit breaker?
The HM632000 is designed specifically for legacy Federal Pacific Electric (FPE) commercial panelboards and switchgear configured for HM-frame, bolt-on circuit breakers.
What does the HM designation indicate on this breaker?
The HM prefix indicates the breaker belongs to the Federal Pacific H-Frame family of molded case circuit breakers. This dictates its physical dimensions and mounting footprint within the switchgear.
Is the Federal Pacific HM632000 still in active production?
No. Federal Pacific Electric is no longer in business, making the HM632000 an obsolete, legacy component. It is typically sourced to maintain existing commercial electrical systems rather than for new installations.
Can the HM632000 be used in a plug-on application?
No. The HM632000 is strictly a bolt-on circuit breaker and must be mechanically bolted to the busbars in compatible Federal Pacific switchgear.
Can the HM632000 be applied to systems operating below 600V?
Yes. While it has a maximum voltage rating of 600VAC, it is fully compatible with lower voltage systems. The breaker provides an interrupting capacity of 35kA at 240VAC and 22kA at 480VAC.
Is the HM632000 affected by the Federal Pacific Stab-Lok safety controversies?
The well-documented safety concerns associated with Federal Pacific primarily involve residential Stab-Lok load centers and breakers. The HM632000 is a commercial-grade HM-frame molded case circuit breaker, which utilizes a different design. However, due to the age of all FPE equipment, regular testing by a qualified professional is recommended.
