Part of the classic N-Frame series, this 200A unit-mount breaker provides essential long-time and instantaneous trip functions for commercial environments. It serves as an exact replacement component for aging Federal Pacific switchboards and motor control centers without requiring aftermarket adapters. Featuring a robust 42kAIC rating at 240V, this thermal-magnetic unit ensures continued operational safety for existing infrastructure.
What enclosures are compatible with the Federal Pacific NJ632200?
This N-Frame molded case circuit breaker is designed as a direct replacement for legacy Federal Pacific (FPE) distribution panels, switchboards, and motor control centers.
Does the NJ632200 require a retrofit kit to mount in an existing FPE switchboard?
No, this is a standard unit-mount breaker that installs directly into compatible Federal Pacific enclosures without requiring aftermarket adapters or retrofit kits.
How is the trip unit configured on the NJ632200?
It features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic threshold is set via a dial on the breaker face.
Is the NJ632200 N-Frame breaker affected by the Federal Pacific Stab-Lok safety issues?
No. The documented safety hazards associated with Federal Pacific primarily involve their residential Stab-Lok plug-in breakers. The NJ632200 is a commercial-grade, molded case N-Frame breaker with a completely different internal mechanism.
Are original Federal Pacific NJ-series breakers still in production?
No, Federal Pacific Electric is no longer in business, and the N-Frame series is obsolete. Replacing a failed NJ632200 requires sourcing legacy stock, as there are no direct drop-in replacements currently manufactured by other brands.
What wire size range is supported by the terminals on this 200A breaker?
The standard lugs on the NJ632200 accept conductors ranging from 4 AWG up to 300 kcmil.
