NA2P100 - Federal Pacific - Stab-Lok Plug-In Circuit Breaker - 100 Amp - 2 Pole - 240 Volt (Used)
Product images are representative only. Actual product may vary.
The Federal Pacific NA2P100 is a 100A, 2-pole thermal-magnetic Stab-Lok plug-in circuit breaker rated 120/240VAC, sized full-width at one inch per pole for original FPE Stab-Lok load centers.
This unit is sold in used condition and carries a 1-year warranty.
A 100A two-pole is the typical main or large subfeed position in a residential or small commercial Stab-Lok panel — feeding a subpanel, a range circuit, or a detached structure. Because Federal Pacific ceased production decades ago and the Stab-Lok bus stab is proprietary, no other manufacturer's breaker will seat properly, which makes original NA-series stock the only direct fit. This unit is the full-size body requiring one inch per pole, with common trip linking both poles and a color-coded handle. Rated 10kA at 120/240VAC.

Frequently Asked Questions
What condition is this NA2P100 in, and is it warrantied?
It is a used unit, tested and sold with a 1-year warranty. Used stock is the practical option for legacy Stab-Lok panels where new-old-stock is scarce.
Will a breaker from another manufacturer fit my Stab-Lok panel?
No. The Stab-Lok bus stab geometry is proprietary to Federal Pacific. Only NA-series breakers or listed Stab-Lok replacements will seat correctly and make proper contact.
What is the difference between full-size and thin Stab-Lok breakers?
Stab-Lok was produced in both a full-size body at one inch per pole and a narrower thin body. They are not interchangeable in all panel positions. The NA2P100 is the full-size format.
Are there known concerns with Federal Pacific Stab-Lok panels?
Yes. Stab-Lok breakers have been the subject of long-standing reports and litigation regarding failure-to-trip under fault conditions, and many inspectors and insurers recommend full panel replacement rather than continued service. Have the installation evaluated by a licensed electrician before deciding between repair and replacement.
What is the interrupting rating of the NA2P100?
10kA at 120/240VAC.
What wire sizes does the NA2P100 accept?
#4 AWG through 2/0 AWG conductors.
Does the NA2P100 have common trip?
Yes. Both poles are internally linked, so a fault on either pole opens the full two-pole circuit.
Can the NA2P100 be used as a main breaker?
In load centers designed with a 100A main breaker position, yes. Verify the panel label for the acceptable main device before installing.
