Rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, the contact ratings cover the typical control-voltage range across global panel designs — 24 VDC for PLC-driven coils, 230 V for line-voltage control circuits, and 400/690 V for higher-voltage auxiliary circuits in IEC markets. The 6 kV rated surge voltage resistance (impulse withstand) means it can live on the same panel as contactors switching motor loads without external surge suppression in most industrial environments. That matters when the auxiliary contactor is used to feedback a status signal to a controller rather than switching a coil directly. Fastening method is screw and snap-on mounting. Width is 45 mm, height 60 mm, depth 73 mm. IP20 protection on the front means it is touch-safe but not washdown-rated — suitable for enclosed control panels, not open-floor mounting. Wire termination accepts 2x (0.25... 2.5 mm²) solid or stranded conductors — the dual-termination allows looping through without a separate terminal block. The screw terminals are the standard box-clamp type on SIRIUS S00 contactors; strip length and torque follow the Siemens mounting instructions. Substance prohibitance date is 07/01/2006. The part is RoHS-compliant for that baseline. Shock resistance is rated at 10g / 5 ms and 5g / 10 ms, which covers the vibration environment of standard industrial panels mounted on machine frames or walls. The 30 million mechanical operations typical life means it outlasts most machine design cycles even under continuous cycling.
