Product FAQs
5 answersWhat type of panels are compatible with the Federal Pacific NP632100?
This breaker is specifically designed for legacy Federal Pacific switchgear and FPE distribution panels that accommodate N-frame molded case circuit breakers.
How does the NP632100 connect to the panel bus?
It utilizes a bolt-on busbar connection. The breaker terminals must be physically bolted to the panel busbars, requiring the panel to be completely de-energized during installation.
Are the trip settings on the NP632100 adjustable?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Is the Federal Pacific NP632100 still in active production?
Federal Pacific Electric (FPE) is no longer manufacturing new equipment. The NP632100 is considered a legacy breaker, so exact replacements are sourced to maintain existing FPE switchgear without requiring a complete panel retrofit.
What should be verified before installing the NP632100 in an existing FPE panel?
Ensure the panel is fully de-energized. You must also verify that the system available fault current does not exceed the 85kAIC rating at 480V and that the busbar spacing matches the NP frame dimensions.
