ED41B050 - 50Amp Circuit Breaker

ED41B050 - 50 Amp Circuit Breaker

The ED41B050 circuit breaker is a 50-amp, single-pole molded case circuit breaker designed to deliver dependable circuit protection in commercial and industrial electrical distribution systems. Built in the Sentron-style ED4 frame, this breaker helps safeguard electrical equipment and branch circuits from overloads and short circuits while maintaining stable performance in demanding environments. Its bolt-on mounting design provides a secure connection to compatible panelboards, helping reduce vibration-related issues and ensuring a stable electrical interface over time.

Rated for 22kA interrupting capacity at 277VAC and 65kA at 120VAC, the ED41B050 offers strong fault-clearing capability where higher available fault currents may be present. The unit is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. With included load-side terminals and reverse-feed capability, it provides flexible installation options for electricians and facility maintenance teams. Designed to operate reliably in environments up to 40°C, this breaker is well-suited for a wide range of electrical protection requirements in modern power distribution systems.
