Description
Providing critical thermal-magnetic protection for 40A applications, this two-pole device supports heavy residential loads like electric ranges. It offers a practical maintenance solution for aging infrastructure. The physical dimensions match classic Federal Pacific Stab-Lok load centers perfectly. As an exact cross-reference for the obsolete NA240, it slides into thick-series panel slots without requiring modifications.Specifications

Product FAQs
6 answersWhat electrical panels are compatible with the UBIF240N circuit breaker?
The UBIF240N is designed exclusively for use in Federal Pacific Electric (FPE) Stab-Lok load centers. It serves as a direct plug-on replacement for legacy FPE panels requiring thick-style breakers.
Which original Federal Pacific breaker does the UBIF240N replace?
The UBIF240N is a direct replacement for the original Federal Pacific NA240 circuit breaker. It fits the same 2-inch thick profile required for FPE Stab-Lok NA series applications.
How does the UBIF240N connect to the load center?
This breaker features a plug-on mounting style, allowing it to stab directly into the busbar of compatible Federal Pacific Stab-Lok panels. It uses standard lug terminals for the load-side wire connections, accepting 14 to 6 AWG wire.
What type of trip mechanism does the UBIF240N utilize?
It uses a fixed thermal-magnetic trip mechanism, providing both long-time thermal protection against overloads and instantaneous magnetic protection against short circuits.
Is the UBIF240N suitable for HVAC applications?
Yes, this 2-pole breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 40A circuit.
Is the UBIF240N a safe replacement for older FPE breakers?
Yes, the UBIF series breakers are newly manufactured to modern safety standards and are ETL listed to UL 489 specifications. This provides a reliable and compliant replacement for aging Federal Pacific Stab-Lok breakers without requiring a full panel upgrade.
