SIRIUS auxiliary contactor, S00 — 3 NO, 10 A
The Siemens 3RH2131-1AB00-ZW96 is a SIRIUS auxiliary contactor in the S00 frame size, delivering three normally-open instantaneous contacts rated at 10 A for both 24 V and 230 V circuits. That 10 A rating at 24 V means it handles control-circuit loads like PLC outputs, relay coils, and indicator lamps without derating — the same contact set also carries 10 A at 230 V for pilot-duty switching on panel feeders. The S00 footprint — 73 mm deep, 45 mm wide, 57.5 mm high — fits tightly in crowded enclosures; the side clearance requirement of just 6 mm leaves room for adjacent devices.
Current ratings across voltages
The contact set is rated across a wide voltage range: 10 A at 24 V and 230 V, 4.7 A at 60 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V (–). The drop at higher voltages reflects the arc-quenching limits of the S00 contactor — for a 690 V control circuit, the 1 A rating is the ceiling, not a derating target.
Operating temperature range -25 to +60 °C, storage -55 to +80 °C, with 10% to 95% relative humidity. Degree of pollution 3 — suitable for industrial enclosures where conductive dust or moisture may be present. Substance prohibitance date 10/01/2009 aligns with RoHS/REACH compliance expectations.
