ED42B110 - 110Amp Circuit Breaker

ED42B110 - 110 Amp Circuit Breaker

The ED42B110 circuit breaker is a 2-pole, 110-amp molded case breaker commonly used in commercial and industrial electrical distribution systems. Built on the ED4 frame platform, it is designed to help protect circuits from overloads and short-circuit conditions while maintaining steady power flow throughout the panel. With an interrupting rating of 18kA at 480VAC and 65kA at 240VAC, the breaker is capable of handling higher available fault currents often found in larger electrical systems. This model uses a bolt-on mounting style, allowing the breaker to fasten directly to the panelboard bus for a solid and dependable connection. Installers will also appreciate that load-side terminals are included, which can make the wiring process more straightforward during installation or replacement work. The ED42B110 carries a HACR rating, meaning it can be used on heating, air-conditioning, and refrigeration circuits. It is designed for 40°C operating conditions, which aligns with most electrical room environments. In addition, the breaker is suitable for reverse feed applications, giving electricians more flexibility when configuring panel layouts or replacing existing breakers in compatible equipment.
