CED63B125 - 125Amp Circuit Breaker

CED63B125 - 125 Amp Circuit Breaker

The CED63B125 circuit breaker is a 3-pole, 125-amp molded case circuit breaker designed for use in commercial and industrial electrical distribution systems requiring high interrupting capacity and dependable overcurrent protection. Built on the CED6 frame and rated for up to 200kA at 240VAC and 480VAC (100kA at 600VAC), this fuseless current-limiting breaker helps protect equipment and conductors from overloads and short circuits. Its bolt-on mounting configuration ensures secure installation, while included load-side terminals simplify field connections. HACR rated and suitable for reverse feed applications, the CED63B125 is engineered for consistent performance in demanding environments operating at 40°C.

Designed with compatibility and function in mind, this breaker is intended as a form, fit, and functional replacement within systems utilizing the CED6 frame type. Its construction reflects the durability expected in industrial power distribution equipment—built to last and to maintain electrical system integrity under specified ratings.
