The Siemens 3RH1122-2AP00-0TK1-ZX95 is a SIRIUS auxiliary contactor in size S00, carrying four normally open instantaneous contacts for control-circuit switching in motor starter and contactor assemblies. Rated for 10 A at 24 V, 6 A at 230 V, and 1 A at 690 V, the contact ratings cover the typical control-voltage range found in industrial panels — 24 VDC for PLC outputs, 230 VAC for line-voltage interlocks, and 690 V for high-potential isolation circuits. Mounting is via screw or snap-on onto a DIN rail, with the enclosure rated IP20 on the front for basic finger protection inside a panel.
Sourcing and Lifecycle
The substance prohibition date of 07/01/2006 confirms RoHS compliance for the European market; no further REACH or UL documentation is carried in the spec record, so for audit purposes the buyer should request the manufacturer's declaration of conformity separately.
Integration Notes
The S00 frame measures 45 mm wide by 60 mm tall by 73 mm deep, fitting the standard contactor footprint used across the SIRIUS 3RH1 and 3RH2 families. Terminals accept solid conductors from 0.25 mm² up to 2.5 mm², which covers the common control-wiring sizes for 1.5 mm² and 2.5 mm² stranded or solid runs. Mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward or backward, giving panel builders flexibility when routing wire bundles around the contactor.
Contact Reliability and Environmental Ratings
Contact reliability is specified at one incorrect switching operation per 100 million operations at 17 V, 1 mA — a dry-circuit rating that matters for PLC-level signals where oxide films on silver contacts can cause intermittent faults. Shock resistance is rated at 10g for 5 ms and 5g for 10 ms, and the operating temperature range is -25 °C to +60 °C, with storage and transport tolerance down to -55 °C and up to +80 °C. Pollution degree 3 classification means the contactor is suitable for industrial environments with conductive pollution or dry non-conductive pollution that becomes conductive due to condensation.
