Description
Part of the legacy EA series, this 100-amp circuit breaker is engineered to maintain and service older commercial electrical systems. It mounts into classic Westinghouse and Cutler-Hammer panelboards, offering an exact fit that bypasses the need for modern retrofitting kits. Rated for 10 kAIC at 240VAC, the two-pole bolt-on MCCB utilizes standard thermal-magnetic trip technology. It provides essential long-time and instantaneous (LI) protection for reliable daily operation.Specifications

Product FAQs
5 answersWhich panelboards accept the EA2100 circuit breaker?
This breaker mounts directly into classic Westinghouse and legacy Eaton or Cutler-Hammer panelboards. It provides an exact bolt-on fit for older commercial electrical systems, bypassing the need for modern retrofitting kits.
Is the EA2100 suitable for DC circuits?
Yes, while primarily used in 240VAC systems, the EA2100 is also rated for 125/250VDC applications. This makes it suitable for specific industrial control or battery backup circuits requiring a 100-amp disconnect.
Does the EA2100 come with terminal lugs?
Yes, this breaker includes standard mechanical lugs that accept 14 AWG to 1/0 AWG wire. Installers must ensure conductors are torqued to the manufacturer specifications printed on the breaker face.
Are the trip settings on the EA2100 adjustable?
No, this breaker features fixed thermal magnetic trip settings for both long-time and instantaneous (LI) protection. It cannot be dialed in for custom selective coordination requirements.
Is the Westinghouse EA2100 still in active production?
The EA2100 is part of a legacy molded case circuit breaker family originally manufactured by Westinghouse, and later supported by Eaton and Cutler-Hammer. Exact replacements are sourced to maintain existing panels without requiring busbar modifications.
