Siemens FXD63B200N Industrial Contactor 3 Phase 200A 600V

Siemens FXD63B200N is a three-pole molded-case circuit breaker (MCCB) from the Sentron FXD6 family, rated for 200 A and up to 600 V AC, designed to protect feeders and motors in industrial switchgear and panelboards. It provides thermal-magnetic protection with a 22 kAIC short-circuit interruption rating at 600 V, and the FD frame supports bolt-on mounting for reliable installation in distribution panels. Typical applications include protecting 3-phase feeders and motor circuits in industrial environments where robust overcurrent protection and fast fault isolation are required; it is suitable for use in control panels, power distribution centers, and machine protection schemes that rely on molded-case breakers for reliable interruption. As part of the FXD family, the device is designed for compact, low-voltage protection with compatibility in standard Siemens distribution equipment and related accessories.
