ED42B020 - 20Amp Circuit Breaker

ED42B020 - 20 Amp Circuit Breaker

The ED42B020 20A 2-pole molded case circuit breaker is designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built in the Sentron-style ED4 frame, this breaker delivers consistent performance while protecting equipment and branch circuits from overloads and short circuits. With an interrupting capacity of 18kA at 480VAC and 65kA at 240VAC, the ED42B020 provides reliable fault protection in demanding electrical environments.

This bolt-on-mounted circuit breaker installs securely into compatible panelboards and distribution equipment, helping reduce vibration or movement that could occur with plug-in styles. The included load-side terminals simplify installation and ensure solid conductor connections. Rated for 20 amperes with a two-pole configuration, this breaker is well-suited for applications requiring dependable protection across two energized conductors. It is also HACR rated and suitable for reverse feed applications, offering flexibility for HVAC systems and other commercial electrical loads. Built to perform in environments up to 40°C, the ED42B020 is a practical solution for maintaining system safety and uptime.
