RKN-3M
Purpose
The block of the relay of control of tension of RKN-3M is intended for protection of consumers of the electric power in case of an exit of tension of a network phase for the established values by means of contacts of the relay brought to a terminal block and also for indication of an operating mode of the block.
Design of system
– The RKN-3M block is executed in the case for installation on a DIN lath.
– On the forward panel of the block are 3 handles of regulation of parameters of the block and Network and Protection indicators.
– In the lower part of the block there are terminal blocks for connection of the block to a network и to the scheme of management.
– Adjustable settings are established by the user depending on parameters of the connected equipment. (Pict. 1).
