The Test Terminal Blocks are for 3 phase, 3 wire or 3 phase 4 wire application for upto 50 A continuous rating at 600 V and generally conform to IEC 60947-7-1.Construction:The base of the Test Terminal Block is made of excellent quality electrical grade black Bakelite moulding powder. The base moulding is provided with integrally moulded barriers between the terminals for complete protection against flashovers. In addition, a Bakelite shield is provided in front to avoid flashover or shorting at Cable entries. A moulded shroud is provided for safety against the voltage terminals.The Test Terminal Block can be fitted to any panel by means of 4 holes provided on the base.All terminals, shorting links, screws, nuts etc. used in the electrical connections are of are bright nickel-plated brass to prevent corrosion and providing high conductivity.
