Product FAQs
6 answersWhat panelboards are compatible with the NEJ233150?
The NEJ233150 is designed for use in legacy Federal Pacific (FPE) commercial and industrial panelboards that accept N-Frame, bolt-on circuit breakers.
What wire sizes are accepted by the load lugs on the NEJ233150?
The load side lugs on this breaker accommodate wire sizes ranging from 4 AWG up to 300 kcmil. Always verify that your conductor material and insulation temperature rating align with the application requirements.
What protection is provided by the LI trip function on this breaker?
The LI designation means the thermal-magnetic trip unit includes Long-Time (L) and Instantaneous (I) protection. The fixed thermal element handles sustained overloads, while the fixed magnetic element provides immediate tripping during short-circuit faults.
Can the NEJ233150 be used in direct current (DC) systems?
Yes, in addition to its standard alternating current rating, this molded case circuit breaker is rated for up to 250V DC, allowing it to be utilized in compatible industrial DC distribution applications.
Are the trip settings on the NEJ233150 adjustable?
No, this breaker features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings. The trip thresholds cannot be modified in the field.
What should be inspected before installing this bolt-on breaker?
Before bolting the NEJ233150 into a legacy Federal Pacific panelboard, inspect the busbars and mounting hardware for signs of pitting, corrosion, or thermal damage. A clean, secure connection is critical to prevent excess resistance and overheating.
