Four catalog numbers, one breaker. The third digit in an NEF number is a factory variant, not a rating - NEF431020R is the same device as NEF433020, NEF435020, NEF437020. Where the panel schedule lists any of the four, this unit fits. What the number does carry is the pole count in the second digit and the amperage in the last three. The NEF range is 480 volts throughout.

Federal Pacific NEF-frame breakers are out of production with no modern drop-in equivalent from the original manufacturer. Connecticut Electric UBIF-series units are sold as verified substitutes. ESP stocks tested reconditioned NEF units across the pole and amperage range for legacy FPE and American NEF panelboards still in service.

More Details

Twenty amperes, three poles, 480 volts. Federal Pacific built one three-pole twenty-amp NEF and issued it under several catalog numbers. The R marks Type NEF-R.

What is "surplus new"?

Surplus new means the item has never been installed or put into service. It may not arrive in its original packaging, but it has never been used.

What does "reconditioned" mean?

Reconditioned items have been inspected, cleaned, and tested to confirm they operate to the manufacturer's original specifications. Every reconditioned item we sell carries a one-year operational guarantee.

How fast will my order ship?

In-stock orders placed before 12pm PST usually ship the same business day via UPS, with tracking provided.
