E2100 - 100Amp Circuit Breaker

E2100 - 100 Amp Circuit Breaker

The E2100 circuit breaker is a 2-pole, 100-amp thermal-magnetic breaker designed for dependable overcurrent protection in electrical distribution systems operating at 120/240VAC. Built on the E frame platform, this breaker features a non-interchangeable trip unit and is rated for operation in environments up to 40°C, making it suitable for many commercial and industrial panelboard applications. Its thermal-magnetic protection mechanism responds to both sustained overloads and short-circuit conditions, helping protect wiring and connected equipment from damage. The unit includes load terminals for straightforward installation and secure electrical connections. Designed to match the form and fit of compatible legacy electrical systems, the E2100 provides a practical replacement option when maintaining existing equipment where the original specifications must be preserved. These breakers were built to last and continue to serve as reliable components in properly maintained electrical infrastructure.
