Product Description P/N: NEF211020
Description
The Federal Pacific NEF211020 is a 20 A molded case circuit breaker designed for single-phase, 277 V applications. This type NEF breaker provides LI (long-time and instantaneous) protection through a non-interchangeable thermal magnetic trip unit. The NEF211020 is a bolt-on style breaker equipped with load-side lugs, offering dependable overcurrent protection in legacy systems, though it is now considered obsolete.

Information About NEF211020
The NEF211020 is part of the NEF Series, a family of molded case breakers historically used in Federal Pacific electrical distribution equipment. Built with a compact molded case and fixed trip mechanism, the design focuses on straightforward protection for single-phase branch circuits. The breaker integrates with NEF-compatible bolt-on panelboards, offering secure installation and stable conductor termination via load-side lugs. Commonly found in older commercial and industrial installations, the NEF211020 provided standard interrupting capability and LI trip functions before the series became obsolete.
Key Features:
- 20 A rating: Suitable for single-phase branch circuit protection.
- 277 V operation: Designed for lighting and commercial power applications.
- Thermal magnetic trip: Provides long-time overload and instantaneous fault response.
- LI trip functions: Supports long-time and instantaneous protective characteristics.
- Bolt-on connection: Ensures secure mounting in compatible panelboards.
- 14 kA interrupt rating: Handles moderate fault levels at 277 V.
- Load-side lugs: Allows direct conductor termination for simplified installation.
- Non-interchangeable trip unit: Maintains consistent protection settings.
The NEF211020 delivers the reliability and precision required for legacy molded case circuit protection in older electrical distribution systems.
