Maintaining older industrial facilities requires precise components like the 45A NE224045 thermal-magnetic breaker. This two-pole unit provides essential overcurrent and short-circuit defense for 240VAC commercial power systems.

Product FAQs
5 answersWhich panelboards accept the NE224045 circuit breaker?
This breaker is engineered for use in legacy Federal Pacific NE panelboards. It bolts directly onto the existing busbars, allowing you to restore power without modifying the original enclosure.
What size wire can I use with the NE224045 breaker?
The factory lugs are sized to accept 14 AWG to 2 AWG conductors. Ensure you torque the terminal lugs to the manufacturer specifications during installation.
How does the LI trip function operate on the NE224045?
The LI designation stands for Long-Time and Instantaneous trip functions. The fixed thermal element provides long-time protection against sustained overloads, while the fixed magnetic element offers instantaneous protection against short circuits.
What does the bolt-on connection mean for installation?
Bolt-on breakers like the NE224045 fasten directly to the panelboard busbars using screws. This creates a highly secure, vibration-resistant electrical connection compared to standard plug-on designs.
Is the Federal Pacific NE224045 still in active production?
No, Federal Pacific Electric (FPE) is no longer in business, making the NE series obsolete. We provide exact-match legacy breakers to help facilities maintain their existing electrical infrastructure.
