Description

Maintaining legacy electrical infrastructure demands precise component matching, which this 20-amp, three-phase unit provides for commercial facilities. The plug-on mounting style ensures seamless integration into Federal Pacific NE-S frame panelboards. Facility managers can utilize this component as a drop-in solution for aging distribution systems. Built with fixed thermal-magnetic trip elements, it handles 18kA fault currents at 240VAC while supporting reverse feed applications.

Product FAQs

6 answers
Which panelboards are compatible with the NES2320 circuit breaker?

This plug-in breaker is engineered exclusively for legacy Federal Pacific NE-S frame panelboards. It is not interchangeable with standard Stab-Lok residential load centers.

What are the wire size requirements for the NES2320 terminals?

The load-side lugs accept wire gauges from 14 AWG to 10 AWG. Installers must verify that the selected wire size matches the 20-amp circuit rating and complies with local electrical codes.

What does the LI trip function on the NES2320 indicate?

The LI designation means the thermal-magnetic trip unit includes fixed Long-Time and Instantaneous protection. The long-time element prevents damage from sustained overloads, while the instantaneous element trips immediately during a short circuit.

Can the NES2320 be utilized in DC power applications?

Yes, while primarily used in 240VAC commercial systems, this breaker is also rated for 250VDC applications with a 5kAIC interrupting capacity.

Does the NES2320 require mounting hardware to install?

No, this is a plug-on molded case circuit breaker. It connects directly to the busbars of an NE-S frame panelboard without the need for separate bolt-on brackets or adapters.

Are there modern cross-references for the Federal Pacific NES2320?

Because Federal Pacific Electric is no longer manufacturing new equipment, exact replacements for the NE-S frame require sourcing legacy NES2320 breakers. Standard modern breakers will not fit the proprietary NE-S busbar configuration.
