Product FAQs
6 answersWhat type of enclosures or panels accept the HM632450 breaker?
This H-frame breaker is specifically designed for installation in legacy Federal Pacific switchgear and panelboards that accommodate bolt-on molded case circuit breakers.
How is the trip unit configured on the HM632450?
It utilizes a thermal-magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal element for overload protection is fixed, while the magnetic instantaneous trip is adjustable to coordinate with downstream loads.
Are Federal Pacific HM-series breakers still in active production?
Federal Pacific is a legacy manufacturer. The HM632450 and other H-frame breakers are no longer actively produced and are primarily sourced to maintain or repair existing electrical infrastructure.
Does this breaker require a specific mounting hardware kit?
As a bolt-on breaker, it secures directly to the panel busbar using bolted connections. You must use the appropriate mounting hardware specified for your legacy Federal Pacific switchgear to ensure a proper and safe connection.
What type of conductor connections are provided on this breaker?
The HM632450 comes equipped with standard lug terminals for terminating your line and load wiring. Ensure conductors are torqued to the manufacturer specifications listed on the breaker label.
Can this breaker be used to replace other Federal Pacific H-frame breakers?
Yes, it can replace other breakers within the Federal Pacific H-frame family, provided the 450A rating, 600V maximum voltage, and available fault current of your system align with this specific model. Always verify panel requirements before installation.
