Product FAQs
6 answersWhat hardware is required to mount this breaker into a Federal Pacific panelboard?
Installing the NFJ434200 requires a specific mounting hardware kit, such as the KCDP2 or NFJ1K, depending on your panelboard type. These kits typically include the necessary cover plates, Z-brackets, and bus connectors for a secure bolt-on installation.
Can I use an HFJ frame breaker to replace the NFJ434200?
Yes. The Federal Pacific HFJ434200 is an exact drop-in replacement for the NFJ434200. It shares the same physical dimensions and mounting hardware requirements while offering a higher interrupting capacity.
Is the NFJ434200 affected by the same safety recalls as Federal Pacific Stab-Lok breakers?
No. The NFJ434200 is a commercial-grade, bolt-on molded case circuit breaker. The widely publicized safety concerns and recalls regarding Federal Pacific equipment primarily apply to their residential Stab-Lok plug-on breakers and load centers, not the heavy-duty N Frame series.
Can the NFJ434200 be installed in a twin branch configuration?
Yes. When equipped with the appropriate dual branch mounting hardware, such as the NFJ1K kit, two NFJ or HFJ frame breakers can be mounted directly across from each other in compatible Federal Pacific CDP panelboards.
Are the trip settings on the NFJ434200 adjustable?
The thermal element for long-time overload protection is fixed, but the magnetic element for instantaneous short-circuit protection is adjustable. This allows electricians to fine-tune the instantaneous trip threshold based on the specific load characteristics.
What are the conductor requirements for the load side lugs?
The factory-installed lugs accept conductors ranging from 4 AWG to 300 kcmil. Always verify that the wire insulation temperature rating aligns with the 40C ambient temperature calibration of the breaker.
