Stainless steel screws. Dimension: H 500mm L 750mm P 500mm Thickness 3 mm Complementary module PT4 / A Basic module Kg. 27,00 PT4 / B Complementary module Kg. 2,00 A B CONNECTIONS AND TECHNICAL FEATURES Connections: Connect the protective conductor to the central part of the earth plate. COMPARED VALUES 6 earth plates Earth plate PT4 Dimension of the digging: Length 28 m < 2 m Depth 0,5 m m Surface needed: 32 m 2 2 m 2 A + B 6 EARTH PLATES Technical features: The PT4 modular earth plate PT4 enables making all the earthing installations. It is the technical and economical solution to realize earth installations. It is particularly indicated when the available surfaces are limited (for example in the centre of towns or in blocks of flats). The special geometrical configuration of the PT4 earth plate offers a performance equivalent to 5 parallel plates, therefore its efficiency is nearly equal to 6 earth plates,.5 meters in length, placed at a distance of 4 meters from one another.
