EC3090 - 90Amp Circuit Breaker

EC3090 - 90Amp Circuit Breaker

When maintaining an existing electrical distribution system, finding the right replacement breaker matters. The EC3090 90 Amp 3-Pole Circuit Breaker is designed for use in compatible Type EC systems, providing the ratings and configuration needed to help keep commercial and industrial electrical equipment operating as intended.

Built with a thermal-magnetic trip mechanism, the EC3090 responds to both sustained overload conditions and short circuits, helping protect connected equipment and electrical circuits. Its 90 amp rating, 3-pole design, and 10kA interrupting capacity at 240VAC make it suitable for a wide range of three-phase power distribution applications. Because it features a non-interchangeable trip unit, it maintains the original protection characteristics required by many existing installations.

Whether you're replacing a worn breaker during scheduled maintenance or sourcing a compatible unit for an older electrical system, the EC3090 offers the form, fit, and function needed for continued operation. Rated for use in environments up to 40°C (104°F) and supplied with load terminals, this breaker is built to provide dependable service in demanding electrical applications.

Where It Works Best

The EC3090 is commonly found in commercial facilities, industrial plants, manufacturing operations, institutional buildings, and other environments where Type EC circuit breakers remain in service. It is particularly well suited for maintaining existing switchboards, panelboards, and distribution systems that require a 90 amp 3-pole thermal-magnetic circuit breaker with a 10kA rating at 240VAC. When maintaining legacy electrical infrastructure, having a breaker that matches the original specifications can help simplify repairs and ongoing maintenance.
