EHB2090 - 90Amp Circuit Breaker

EHB2090 - 90 Amp Circuit Breaker

If you're working with an older panel and need a circuit breaker that fits exactly right, the EHB2090 is built for that job. Designed specifically for EHB frame panelboards manufactured before 1989, this 2-pole, 90-amp breaker gives you the confidence of a proper match—no guesswork, no modifications. This is a thermal-magnetic circuit breaker, which means it handles both everyday overloads and sudden short circuits with precision. The fixed, non-interchangeable trip unit keeps performance consistent, while the 14kA interrupting rating at 480VAC provides the protection capacity required for many commercial and industrial setups. It also comes with load terminals included, helping simplify installation when replacing an existing unit. In short, this breaker does exactly what you need it to do: fit your system, protect your circuits, and keep your equipment running as intended. These units were built to last—and when matched correctly, they continue to perform reliably in the field.
