The Siemens 3RH1140-1AP00-ZW98 is a SIRIUS auxiliary contactor in size S00, carrying 4 instantaneous normally-open contacts. Rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, it covers a wide range of control voltages common in global installations.
The IP20 front protection means it is safe for finger contact inside an enclosure but not for direct washdown exposure.
Shock resistance of 10g for 5 ms and 5g for 10 ms means it withstands typical vibration and impact in transport and operation on machinery. The product extension auxiliary switch is available, meaning the base contactor can be fitted with additional contact blocks if more than 4 NO contacts are needed later.
RoHS compliance is confirmed by the substance prohibition date of July 1, 2006, covering the original EU RoHS directive. No REACH or UL listing is stated in the available data, but as a Siemens industrial control product it typically carries CE marking for the European market.
