Siemens Siprotec 4 SIPROTEC 6MD63 Bay Controller Unit

The SIPROTEC 6MD63 Bay Controller unit is a flexible, easy-to-use control unit. It is optimally tailored for medium-voltage applications but can also be used in high-voltage substations.The 6MD63 bay control unit has the same design (look and feel) as the other protection and combined units of the SIPROTEC 4 relay series. Configuration is also performed in a standardized way with the easy-to-use DIGSI 4 configuration tool.For operation, a large graphic display with a keyboard is available. The important operating actions are performed in a simple and intuitive way, e.g. alarm list display or switchgear control. The operator panel can be mounted separately from the relay, if required. Thus, The design ensures flexibility in the unit’s mounting position.Especially, Integrated key-operated switches control the switching authority and authorization for switching without interlocking.
