Siemens CJD63L400 is a molded case circuit breaker designed for providing instantaneous magnetic-only protection against short-circuit faults in three-phase industrial power distribution systems. It features a 400A current rating and a 600V voltage rating, housed within a robust JD frame with a bolt-on connection for secure installation. This breaker is constructed for demanding applications, supporting copper conductors from AWG 3/0 to 500 KCMIL and aluminum from AWG 4/0 to 500 KCMIL, and is compliant with relevant industry standards. Its 150kA interrupting capacity at 480V makes it suitable for protecting feeders and branch circuits in commercial and industrial panels, switchboards, and motor control centers.
