General :

Indotech Test Terminal Blocks  have been designed to facilitate the testing of various equipments like KWH meters, Maximum Demand Indicators, Trivector Meters and Ammeters etc, without disconnecting the existing wiring.

Technical Specifications:

Indotech Test Terminal Blocks are available for 3 phase 3 wire and 3 phase 4 wire, for back connection type.

Maximum Rated Current : 50A  Maximum Rated Voltage: 660V     Diameter of entries : 4mm

Construction:-

a) CURRENT CURCUIT

For each current circuit there are three terminal inserts.A link bar insulated from the terminal insert is provided along the axis of the block across each set of these blocks by means of three screws in the link bars.
By unscrewing or screwing the screw, the current coil can be disconnected or connected.Thus it is possible to test the equipment without interrupting the current circuit.

B) VOLTAGE CIRCUIT

The voltage terminals are so designed that incoming and outgoing leads can be connected or disconnected by adjustment of the position of the movable links.
