Siemens CJ3B125 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 125A continuous current rating and a 600V AC voltage rating, housed within a robust thermal-magnetic trip unit that offers combined long-time and instantaneous (LI) protection functions. The breaker's 3-pole, bolt-on configuration ensures a secure connection, and it is constructed to meet rigorous industrial standards, including an interrupting capacity of 100kA at 480V AC for effective fault containment. Typical applications include protecting feeders, branch circuits, and equipment within industrial control panels and switchgear.
