Contact protection relays are used in type 821 contact devices. They increase the switching reliability and switching capacity of electromechanical contact devices and lower their contact voltage. Undesired switching operations of contact devices caused by vibrations are significantly reduced by a drop-out delay of 0.5 sec. On the side of the contact they operate with a lower control voltage, however, on the output side they can be highly loaded. Contact protection relays consist of a power supply unit, control unit, switching amplifier and relay output. The contacts are supplied by a control unit with 35 to 40 V clocked DC (i.e. only every hundredth switching occurs under voltage). This enables the optimum contact protection and switching reliability for millions of switching cycles.

the 6md66 high-voltage bay control unit is the control unit for high voltage bays from the siprotec 4 relay series. Because of its integrated functions, it is an optimum, low-cost solution for high-voltage switch bays. The 6md66 high-voltage bay controller unit also has the same design (look and feel) as the other protection and combined units of the siprotec 4 relay series. Configuration is performed in a standardised 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 switch gear control. The operator panel can be mounted separately from the unit, if required. Thus, flexibility with regard to the mounting position of the unit is ensured. Integrated key-operated switches control the switching authority and authorisation for switching without interlocking.
