EHB3090L - 90Amp Circuit Breaker

EHB3090L - 90Amp Circuit Breaker

When you're maintaining an existing electrical system, using the right replacement breaker helps keep everything operating as intended. The EHB3090L 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 EHB3090L provides the correct form, fit, and function to maintain compatibility with your existing electrical distribution system.

This breaker uses a thermal-magnetic trip mechanism that responds to both overloads and short circuits, helping protect electrical equipment during everyday operation. It features a non-interchangeable trip unit, is rated at 14 kA at 480 VAC, and carries a 40°C ambient temperature rating. For added convenience, the EHB3090L includes both line and load terminals, making it well suited for compatible installations that require both connections.

Where It Works Best

The EHB3090L is commonly used in commercial buildings, industrial facilities, and other locations where Type EHB circuit breakers remain in service. It's a practical choice for replacing an existing breaker during scheduled maintenance, electrical repairs, or servicing panelboards manufactured before 1989. Because it includes both line and load terminals, it provides the proper form, fit, and function for compatible legacy installations while helping preserve the original configuration of the electrical system.
