Product FAQs
5 answersWhat type of electrical panels is the 3P100 circuit breaker compatible with?
This breaker is designed exclusively for use in legacy Federal Pacific Electric (FPE) Stab-Lok load centers and enclosures. It features the proprietary Stab-Lok plug-in connection and will not fit in panels from other manufacturers.
What are the alternate part numbers for the Federal Pacific 3P100?
The 3P100 is a direct replacement for older Federal Pacific and American Circuit Breaker NA3100 models. It may also be cross-referenced as UBI3100 or 3P100-FLAT-TOP depending on the manufacturer.
How much panel space does this 3-pole Type NA breaker require?
As a Type NA breaker, it features the standard 1-inch width per pole. Because it is a 3-pole breaker, it requires three full 1-inch spaces (3 inches total) in a Stab-Lok load center.
What wire gauge is accepted by the load lugs on the 3P100 breaker?
The load side lugs on this 100A breaker are designed to accept wire ranging from 14 AWG up to 1/0 AWG. Ensure your conductors are sized appropriately for a 100A load per NEC guidelines.
What type of trip mechanism does the 3P100 utilize?
This breaker features a fixed thermal-magnetic trip unit, designated by the LI function code. It provides long-time delay for standard overload protection and an instantaneous trip response for short circuits.
