Product FAQs
4 answersWhat equipment is the Federal Pacific NJJ221350 designed to fit?
This N-frame molded case circuit breaker bolts directly into legacy Federal Pacific Electric (FPE) commercial distribution panels and switchboards. It is not compatible with residential Stab-Lok load centers.
How are the load side connections configured on the NJJ221350?
The breaker is equipped with mechanical load lugs designed for dual conductors. Each phase can accept two wires ranging from 3/0 AWG to 250 kcmil.
Is the trip unit on the NJJ221350 adjustable?
No, this breaker features a non-interchangeable thermal-magnetic trip unit. Both the Long-Time (thermal) and Instantaneous (magnetic) trip functions are fixed at the factory and cannot be adjusted in the field.
Does the NJJ221350 fall under the residential Stab-Lok safety concerns?
No. The NJJ221350 is a commercial-grade, bolt-on N-frame breaker used in heavy distribution equipment. It does not use the Stab-Lok plug-on design associated with residential FPE load centers.
