This unit is sold reconditioned, inspected and tested to ESP Product Standards, and guaranteed to operate normally for one year from the date of sale.

Original manufacture, individually tested. This is an original Federal Pacific Stab-Lok breaker — the part the panel was built around — inspected and tested to ESP Product Standards, individually tested to confirm it trips before it ships, and backed by a one-year operational guarantee.The widely sold alternative is the Connecticut Electric UBIF series, newly manufactured by a third party and ETL listed to UL 489 at 10,000 AIC as a compatible replacement rather than an original part. Both have a case.

Two things decide whether this fits. Body width first: type NA is the thick series and type NC is the thin, and a Stab-Lok load center takes them in different positions. Then the numbering — Federal Pacific used two forms on this line. A two-digit number like NA30 is single-pole; a three-digit number like NA230 is two-pole thirty-ampere. This is the thick series, 1-pole.

Federal Pacific Stab-Lok breakers are out of production.Type NA is the THICK series. Connecticut Electric distinguishes the two the same way in its UBIF replacement line. ESP stocks tested original units for Stab-Lok panels still in service.

More Details

Stab-Lok panels are still in service in thousands of homes, and the original breakers stopped being made decades ago. Two things are available today. Connecticut Electric's UBIF line is newly manufactured by a third party and ETL listed as a compatible replacement. This is the other option: an original unit, made for this panel, individually tested to confirm it trips before it ships. Get the body width right and the pole count right and the rest follows. Type NA is thick, type NC is thin. A two-digit catalog number is single-pole; a three-digit one carries the pole count in the first digit. A panel refit or a maintenance stock can be filled from a single batch, all tested, all guaranteed. Ten kiloamperes interrupting, HACR rated, one-year operational guarantee.

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.
