Product FAQs
3 answersWhat equipment is compatible with the NJ631200 circuit breaker?
This N-frame breaker is designed for bolt-on installation in legacy Federal Pacific commercial panelboards and switchboards. It will not fit in standard residential load centers or Stab-Lok enclosures.
Can the trip settings on the NJ631200 be adjusted in the field?
The thermal (Long-Time) trip setting is fixed at 200 amps. However, the magnetic (Instantaneous) trip function is adjustable, allowing electricians to fine-tune the short-circuit response for proper selective coordination.
Does the NJ631200 share the safety issues associated with Federal Pacific Stab-Lok breakers?
The NJ631200 is a commercial N-frame molded case circuit breaker with a secure bolt-on connection. It is entirely different from the residential Stab-Lok plug-on breakers, which are the primary focus of Federal Pacific safety concerns and failure-to-trip reports.
