CED63B125L - 125Amp Circuit Breaker

CED63B125L - 125 Amp Circuit Breaker

The CED63B125L is a 125 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 platform, this breaker delivers precise overcurrent protection while maintaining the proper form, fit, and function required for compatible panelboards and switchgear. With high interrupting capacity ratings—200k AIC at 240VAC and 480VAC, and 100k AIC at 600VAC—it is well suited for facilities where fault current levels demand a breaker capable of safely clearing short circuits. Rated for 40°C operation and HACR applications, the CED63B125L is engineered for long service life in demanding electrical environments. Line- and load-side terminals are included, and the breaker is suitable for reverse feed installation, offering flexibility during maintenance or system configuration.
