EHB3090 - 90Amp Circuit Breaker

EHB3090 - 90Amp Circuit Breaker

Finding the right replacement breaker is important when you're working on an existing electrical system. The EHB3090 is a 3-pole, 90 amp thermal-magnetic circuit breaker designed for Type EHB applications in panels manufactured before 1989. If your equipment was originally built for this breaker style, the EHB3090 provides the correct form, fit, and function to help keep your system operating as intended.

This breaker uses a thermal-magnetic trip mechanism that responds to both overloads and short circuits, helping protect electrical equipment during normal operation. It features a non-interchangeable trip unit, carries a 14 kA interrupting rating at 480 VAC, and is rated for 40°C ambient conditions. Load terminals are included, so you have the connections needed for compatible installations.
