Test Terminal Block Cut out diag. for 3? - 3W TTB Description :- The test block and the cover are made of black Bakelite moulding. The moulded barriers are provided in base between adjacent terminals to give complete protection against flash over. The cover is swcured in place by knurled sealing nuts. All terminals, shorting links, screws are of brass and nickel plated to prevent corrosion. Terminal Arrangement :- The basic terminal arrangement consists of three voltage terminals with two sets of current terminals.
