EH2B100 - 100Amp Circuit Breaker

EH2B100 - 100 Amp Circuit Breaker

If you’re working on an existing system that calls for an EH2 frame breaker, the EH2B100 is a straightforward, no-surprises replacement. It’s built to match the form and fit you need, so you can get your system back up and running without having to modify your setup or second-guess compatibility. This 2-pole, 100-amp molded case circuit breaker is commonly used in commercial and industrial applications where consistent circuit protection is required. With interrupting ratings of 14k A.I.C. at 480VAC and 18k A.I.C. at 240VAC, it’s designed to safely handle fault conditions while protecting connected equipment. The thermal-magnetic trip mechanism reacts to both overloads and short circuits, helping maintain stable operation in day-to-day use. It’s also built with real-world conditions in mind. Rated for 40°C ambient environments, the EH2B100 holds up in electrical rooms and facilities where heat and load demands are part of the job. Simply put, it does exactly what it’s supposed to do—fit right, work consistently, and last.
