ED42B050 - 50Amp Circuit Breaker

ED42B050 - 50 Amp Circuit Breaker

The ED42B050 molded case circuit breaker is designed to provide dependable protection for electrical distribution systems in commercial and industrial environments. Rated at 50 amps with a 2-pole configuration, this breaker helps safeguard circuits from overloads and short-circuit conditions while maintaining steady performance under typical operating temperatures. Built on the ED4 frame platform, the ED42B050 is commonly used in panelboards that require bolt-on style breakers for a secure and stable connection.

This breaker features an interrupting rating of 18kA at 480VAC and 65kA at 240VAC, allowing it to safely interrupt high fault currents when they occur. The unit is HACR rated, making it appropriate for heating, air conditioning, and refrigeration equipment circuits often found in commercial facilities and mechanical systems. For installation convenience, the breaker includes load-side terminals and can be used in reverse feed applications when required. Calibrated for 40°C operation, the ED42B050 is built to maintain consistent protection in electrical rooms, distribution panels, and equipment installations where reliable circuit control is essential.
