EB2100 - 100Amp Circuit Breaker

EB2100 - 100 Amp Circuit Breaker

The EB2100 circuit breaker is a 2-pole, 100-amp thermal-magnetic breaker designed for dependable circuit protection in legacy electrical distribution systems. Built on the EB frame, this breaker is rated 10k A.I.C. at 120/240VAC and is intended for installation in panelboards manufactured prior to 1989 that require EB-series breakers with non-interchangeable trip units. Its thermal-magnetic trip mechanism helps respond to both prolonged overloads and short-circuit conditions, helping protect wiring and connected equipment from electrical faults. The EB2100 includes load terminals for secure conductor connections and is 40°C rated, making it suitable for typical commercial and industrial electrical environments. Designed with long-lasting construction and reliable operation in mind, this breaker provides the proper form, fit, and function replacement needed to maintain existing systems without altering the original panel configuration.
