Siemens SIRIUS 3RT1055-2AD36 — Power Contactor, Size S6
It carries a 42-48 V AC/DC coil (rated value 42-48 V) and includes an auxiliary switch (auxiliary switch yes). The main circuit accepts stranded conductors from 25 to 120 mm² (stranded 25-120 mm²), while the auxiliary circuit takes solid or stranded 2x 0.25-2.5 mm² (solid 2x 0.25-2.5 mm²). Coil termination uses spring-type terminals (of magnet coil spring-type terminals).
Fastened via screw fixing (fastening method screw fixing) through a single 9 mm hole (number of holes 1, diameter of holes 9 mm). Mounting position allows vertical surface with +/-90° rotation and +/-22.5° tilt forward/backward (mounting position with vertical mounting surface +/-90° rotatable, with vertical mounting surface +/-22.5° tiltable to the front and back). Dimensions: width 120 mm, height 172 mm, depth 170 mm (width 120 mm, height 172 mm, depth 170 mm). Clearance distances: upwards 10 mm, downwards 10 mm, forwards 20 mm, at the side 10 mm (upwards 10 mm, downwards 10 mm, forwards 20 mm, at the side 10 mm).
