Product FAQs
4 answersCan the NEF421030 be installed in standard Federal Pacific Stab-Lok residential panels?
No, the NEF421030 is a commercial N-Frame bolt-on breaker. It is not compatible with residential Stab-Lok load centers and is designed exclusively for NEF and CDP series panelboards.
Are the thermal and magnetic trip elements adjustable on the NEF421030?
No, this N-Frame breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-sealed and cannot be modified in the field.
Is the NEF421030 still actively manufactured by Federal Pacific?
No, Federal Pacific Electric (FPE) is no longer in business, making the NEF series a legacy product line. These breakers are sourced to maintain and service existing NEF and CDP panelboards without requiring a full system retrofit.
Does the NEF421030 require aftermarket mounting adapters for installation?
No, this breaker is engineered as an exact replacement component. It bolts directly into the chassis of compatible Federal Pacific NEF and CDP panelboards using standard hardware.

Superbreakers did a great job for us. We called and asked if the breakers were actually in their possession. Withing 30 minutes they called us back (which is rare these days), and we got our breakers the next morning.
