Description
Maintaining operational continuity in older commercial facilities requires exact-match components like this 50-amp thermal-magnetic breaker. Built specifically for Federal Pacific NE panelboards, it eliminates the need for complex retrofits or panel upgrades. This unit shares compatibility with the UBINE233050 substitute SKU. The bolt-on configuration ensures a secure mechanical connection, while the 18kAIC rating at 240VAC handles standard fault currents safely.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the NE233050 circuit breaker?
This breaker is designed exclusively for installation in legacy Federal Pacific NE series panelboards.
Is there a modern aftermarket replacement for the Federal Pacific NE233050?
Yes. The UBINE233050, manufactured by Connecticut Electric (UBI), serves as a direct aftermarket substitute for this obsolete Federal Pacific breaker.
How does the NE233050 mount into the panelboard?
It is a bolt-on molded case circuit breaker that bolts directly to the busbars of compatible Federal Pacific NE panelboards. It does not snap in or mount to a DIN rail.
What wire sizes do the load-side lugs on this breaker accept?
The factory-installed load lugs are sized to accept 14 AWG to 2 AWG conductors. Always torque the terminals to the manufacturer specifications listed on the breaker label.
Is the NE233050 rated for use in direct current (DC) systems?
Yes. In addition to its 18kA at 240VAC rating, this breaker is rated to interrupt up to 5kA at 250VDC.
Does this breaker feature an adjustable trip setting?
No. The NE233050 utilizes a fixed thermal-magnetic trip unit that provides long-time and instantaneous (LI) protection. The trip points cannot be adjusted in the field.
