Protective conductor terminal blocks are used to form the electrical and mechanical connection between copper conductors and the fixing support.<\/p>\n
lt is applicable to protective conductor terminal blocks for the connection of round copper conductors with or without special preparation having a cross-section between 0,2 mm2<\/sup> and 120 mm2<\/sup> (AWG 24 and 250 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up to 1 000 Hz or 1 500 V d.c., most commonly in conjunction with terminal blocks according to IEC 60947-7-1.<\/p>\n
