E2100 - 100Amp Circuit Breaker

E2100 - 100Amp Circuit Breaker

When you're working on an existing electrical panel, especially one that's been in service for a long time, the main goal is usually to replace like-for-like so everything continues operating the way it was originally designed. The E2100 100 Amp 2-Pole Circuit Breaker is built for that kind of job. It’s a Type E thermal-magnetic breaker used in systems that require a 100 Amp rating, 2-pole configuration, and 120/240VAC service.

The E2100 is rated for a 10kA interrupting capacity at 120/240VAC, making it suitable for a variety of general replacement applications within its listed electrical limits. It also includes a non-interchangeable trip unit, which helps preserve the original factory configuration of the equipment it’s installed in. With a 40°C temperature rating and included load terminals, it fits into compatible panels without requiring changes to the existing layout or wiring setup.

In the field, this breaker is typically used during maintenance or replacement work where keeping the original system design intact is the priority. Matching the correct amperage, pole configuration, and voltage rating helps ensure the electrical system continues to operate as intended.
