CED63B050L - 50Amp Circuit Breaker

CED63B050L - 50 Amp Circuit Breaker

The CED63B050L is a 50-amp, 3-pole fuseless current-limiting molded case circuit breaker designed for dependable circuit protection in commercial and industrial power distribution systems. Built on the CED6 frame, this breaker delivers high interrupting capacity—up to 200kA at 240VAC and 480VAC—making it well-suited for applications where available fault current is significant. Rated for 40°C operation and HACR applications, the CED63B050L provides consistent thermal-magnetic protection against overloads and short circuits. It includes both line- and load-side terminals and is suitable for reverse feed installations, offering flexibility when matching existing panel configurations or replacing like-for-like components in legacy systems. Constructed for long-term service, this breaker is built to last while maintaining proper form, fit, and function within compatible equipment.
