Stands upright on a horizontal surface — that's the only allowed mounting position. Mechanical life is 30 million cycles typical.
Can also take two conductors per terminal: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm². Coil terminals are screw-type — no spring cage here. Strip and torque per standard Siemens practice for this contactor series.
Operating Conditions and Ratings
Switching frequency depends on duty: AC-1 resistive loads up to 1000 ops/h, AC-2 and AC-3 motor loads up to 750 ops/h, AC-4 plugging/reversing up to 250 ops/h. At 48 V rated value is 2 A, at 60 V also 2 A, at 110 V it's 1 A, at 125 V it's 0.9 A, at 220 V it's 0.3 A, at 400 V it's 3 A, at 440 V it's 0.2 A. At 230 V it's rated for 1 hp.
