Product FAQs
4 answersWhat equipment is compatible with the HM632600 circuit breaker?
This H-frame breaker is specifically designed for installation in legacy Federal Pacific switchgear and panelboards. It is not interchangeable with modern panels from other manufacturers.
Can the HM632600 replace the discontinued NM632600 breaker?
Yes, the HM632600 serves as a direct substitute for the obsolete Federal Pacific NM632600. This allows facilities to maintain existing legacy panels without requiring a full system retrofit.
How do I adjust the trip settings on this breaker?
The HM632600 features a thermal magnetic trip unit with a fixed thermal element for long-time overload protection. The magnetic instantaneous trip is adjustable, allowing electricians to fine-tune short-circuit protection for specific loads.
What safety protocols apply when installing legacy Federal Pacific breakers?
Always de-energize the switchgear before installation. Because this is a legacy component, a licensed electrician should verify busbar integrity, ensure bolt-on connections are torqued to the original manufacturer specifications, and perform standard insulation resistance testing prior to commissioning.
