Product FAQs
3 answersWhat panelboards are compatible with the NEF631030 circuit breaker?
This bolt-on circuit breaker is designed for installation in legacy Federal Pacific Electric (FPE) panelboards and switchboards that accept N-frame breakers.
Are there direct replacements available for the Federal Pacific NEF631030?
Yes, the HEF631030 is a direct bolt-on replacement that fits into the same Federal Pacific panelboards without requiring aftermarket adapters. It offers a higher interrupting capacity for facilities requiring upgraded fault protection.
Are there safety concerns associated with legacy Federal Pacific Electric (FPE) equipment?
Yes, legacy FPE equipment has a documented history of reliability issues, with some breakers failing to trip during overload conditions. While the NEF631030 is a commercial molded case breaker rather than a residential Stab-Lok model, many facilities choose to upgrade legacy FPE panels to meet modern safety standards.

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.
