Product FAQs
5 answersCan I install the NJL632150 in a modern Square D or Eaton panel?
No. The NJL632150 is an N-Frame breaker specifically designed for legacy Federal Pacific Electric (FPE) switchboards and panelboards. It is not interchangeable with modern Square D, Eaton, or other contemporary panelboards.
How does the trip unit function on the Federal Pacific NJL632150?
This breaker utilizes a thermal-magnetic trip unit with LI (Long-Time, Instantaneous) functions. It features a fixed thermal setting for overload protection and an adjustable magnetic setting, allowing you to fine-tune the instantaneous short-circuit response.
What are the terminal specifications for wiring the NJL632150?
The breaker comes equipped with lug terminals that accommodate wire sizes from 6 AWG up to 300 kcmil. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Is the Federal Pacific NJL632150 still in active production?
No. Federal Pacific Electric (FPE) is no longer in business, making original NJL frame breakers obsolete. However, exact-fit replacements are still available to maintain aging FPE commercial electrical systems without requiring complete panel modifications.
Is the NJL632150 part of the recalled Federal Pacific Stab-Lok residential line?
No. The NJL632150 is a commercial-grade, bolt-on molded case circuit breaker (N-Frame) used in heavy-duty switchboards and panelboards. It is entirely different from the residential Stab-Lok plug-on breakers that are commonly associated with safety recalls.
