Manufactured to modern safety standards, the UBIF0230 is a 2-pole, 30A miniature circuit breaker for residential and commercial use. It provides reliable thermal-magnetic trip protection for 120/240V circuits. Serving as an exact cross-reference for the legacy NC230, it mounts into classic Federal Pacific Stab-Lok load centers. It maintains the original half-inch per pole thin-series footprint without requiring panel modifications. This HACR-rated breaker features a 10kA interrupting capacity.
The UBIF0230, also listed as UBIF0230N, is a direct replacement for Federal Pacific Electric (FPE) Stab-Lok NC230 circuit breakers. It is manufactured by Connecticut Electric to fit existing FPE Stab-Lok load centers.
Is the UBIF0230 a thick or thin series breaker?
This is a Type NC thin series breaker. It features a half-inch per pole design, meaning this 2-pole breaker requires only 1 inch of total space on the panel busbar.
What wire gauge is accepted by the lugs on the UBIF0230?
The terminal lugs on this breaker accept copper or aluminum wire sizes from 14 AWG to 8 AWG.
Is the UBIF0230 HACR rated?
Yes, this breaker is HACR rated. It is suitable for use with heating, air conditioning, and refrigeration equipment that requires a 30-amp, 2-pole circuit.
Are UBIF series replacement breakers safe to use in original FPE panels?
Yes. While original Federal Pacific breakers have a documented history of safety issues, UBIF series replacements are newly manufactured by Connecticut Electric and tested to meet modern safety standards for existing Stab-Lok load centers.
How does the UBIF0230 connect to the panel busbar?
It features a plug-on connection designed exclusively for Federal Pacific Stab-Lok load centers. It is not interchangeable with plug-on breakers from other brands.
