EC3020 - 20Amp Circuit Breaker

EC3020 - 20 Amp Circuit Breaker

The EC3020 circuit breaker is a 3-pole, 20-amp thermal-magnetic breaker designed for dependable circuit protection in electrical distribution systems operating up to 240VAC. Built on the EC frame platform, this breaker provides the correct form, fit, and function needed for maintaining or replacing components in compatible panelboards and switchgear. Its thermal-magnetic trip mechanism with a non-interchangeable trip unit helps protect conductors and equipment from overloads and short circuits, while the 40°C ambient rating supports reliable operation in typical electrical room environments. With a 10kA interrupting rating at 240VAC, the EC3020 is suited for many commercial and industrial applications where maintaining legacy system compatibility is important. The unit ships with load terminals included, helping simplify installation in appropriate equipment configurations. Designed with durable internal components and a straightforward breaker format, this model reflects the long-lasting construction typical of breakers used in established electrical systems.
