E2090 - 90Amp Circuit Breaker

E2090 - 90Amp Circuit Breaker

When you're working in an existing electrical panel, the goal usually isn’t to change anything—it’s to get the system back up and running with the right replacement part. The E2090 90 Amp 2-Pole Circuit Breaker is designed for that kind of work. It’s a Type E thermal-magnetic breaker used in systems that require a 90 Amp rating, 2-pole configuration, and 120/240VAC service.

The E2090 carries a 10kA interrupting rating 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 maintain the original factory configuration of the equipment it’s installed in.

In the field, this breaker is typically used during maintenance or replacement work in established systems—especially when keeping the original electrical design intact is the priority.
