Product FAQs
6 answersWhich panelboards are compatible with the NM632000?
The NM632000 is compatible with Federal Pacific Electric (FPE) switchboards and panelboards designed to accept NM frame molded case circuit breakers. Always verify busbar spacing and mounting hardware before installation.
How does the thermal magnetic trip unit on the NM632000 operate?
The thermal magnetic mechanism provides two layers of protection. The thermal component offers long time delay protection against gradual overloads, while the magnetic component provides instantaneous tripping to quickly clear severe short circuits.
What are the advantages of the bolt-on connection for this 800A breaker?
The bolt-on mounting style provides a highly secure, vibration-resistant connection to the panel busbars. This is critical for maintaining stable electrical contact and preventing arcing in high-amperage 3-phase industrial applications.
Are there aftermarket alternatives for the Federal Pacific NM632000?
Yes. Since original Federal Pacific Electric breakers are obsolete, exact drop-in replacements for the NM632000 are frequently sourced through American Circuit Breaker (ACB) or Challenger. These aftermarket options share the same physical dimensions and NM frame specifications.
How should the load side conductors be terminated on the NM632000?
Conductors are terminated using load side lugs. Because this is an 800 amp breaker, installers must ensure the lugs are properly torqued to the manufacturer specifications and are rated for the specific size and material of the incoming cables.
Can the NM632000 be used on 480V or 240V systems?
Yes. While the breaker has a maximum voltage rating of 600V AC, it is fully compatible with lower voltage 3-phase systems, including 480V and 240V applications.
