EB2090 - 90Amp Circuit Breaker

EB2090 - 90 Amp Circuit Breaker

The EB2090 circuit breaker is a 2-pole, 90-amp thermal-magnetic circuit breaker designed for use in legacy electrical distribution systems installed prior to 1989 that utilize EB-frame breakers. Built to provide dependable circuit protection in compatible panelboards, this breaker helps guard electrical systems against overloads and short circuits through its integrated thermal-magnetic trip mechanism. The non-interchangeable trip unit ensures that the breaker operates within its intended rating, maintaining the original panel configuration and electrical protection design. Rated for 10kA interrupting capacity at 120/240VAC and calibrated for 40°C environments, the EB2090 is suited for commercial, industrial, and facility maintenance applications where maintaining compatibility with existing equipment is essential. Load terminals are included to simplify installation and maintain proper electrical connections in compatible panels.

Products in the EB frame family were engineered for durability and long service life in electrical distribution systems. When a replacement breaker is required to restore service or maintain an existing panel configuration, the EB2090 offers the proper form, fit, and function for systems originally designed around this breaker type.
