The Siemens 3RH2131-1AN60 is a SIRIUS auxiliary contactor in frame size S00, carrying three normally-open instantaneous contacts. Mechanical endurance is listed at 30,000,000 operating cycles typical, which reflects the S00 frame's duty in high-cycle signalling and interlocking applications rather than main power switching.
Panel fit and mounting envelope
These are the minimum air gaps to adjacent metalwork or other devices for the rated insulation voltage — a panel layout that pinches these clearances risks flashover at pollution degree 3.
Rated operational current across the voltage range
The steep derating above 400 V reflects the arc extinction limits of the S00 air-break contact system.
Pollution degree 3 means the contactor is rated for conductive pollution environments typical of industrial control panels without a sealed enclosure. The part carries a RoHS compliance substance prohibition date of 10/01/2009, confirming it meets the original RoHS directive. Relative humidity minimum is 10 % — no upper humidity limit is listed in this record, so the storage envelope should be treated as the standard IEC 60068-2-30 damp-heat cyclic profile unless the full datasheet specifies otherwise.
