Melamine Disconnect & Test Terminal Blocks

These blocks are used for measuring, control, regulatory circuits and for current transformer connection application. They provide a clear functional advantage for devices having utility instruments and associated transformers. In CMDT4 terminal the disconnection of circuit is achieved by means of a central sliding link assembly with a clear orange indicator. In the CMDT4S Terminal Block the orange indicator is replaced by a socket headed screw for achieving the circuit disconnection. Cross connection is possible with the aid of external jumpers. Barrel nuts provide test sockets for inserting test plugs and for carrying out current and voltage injection protocols.
