At 10 mm wide, it occupies minimal DIN-rail space alongside the contactor — a key advantage when packing multiple auxiliaries into a tight panel. The IP20 front protection means it is safe for finger contact inside an enclosed panel but not for exposed washdown areas. That is the maximum continuous current the contacts can carry in a resistive circuit at that voltage. For inductive or motor-control loads, the switching capacity drops significantly: at 48 V it is rated 2 A, at 110 V it drops to 1 A, and at 220 V it handles 0.3 A. These are the AC-15 / DC-13 style derated values for pilot-duty switching of contactor coils, solenoid valves, and indicator lamps. The rated operational currents at higher voltages follow a similar derating curve: 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, and 0.26 A at 600 V. For a 690 V AC-15 circuit, the rated current is 1 A. These numbers govern the actual load you can switch, not the thermal rating — use the voltage-specific row, not the 24 V headline, when sizing for a 400 V or 480 V control circuit. For a critical-spare holding or a BOM freeze, this part is a straightforward line item to quote against an RFQ. The snap-on S00 footprint is shared across the SIRIUS 3RT2 contactor family, so a spare in the cabinet covers multiple contactor sizes in the same frame. ## Wiring and integration notes Terminals accept 2 x (0.5 to 1.5 mm²) solid or 2 x (0.75 to 2.5 mm²) stranded with ferrules, or 2 x (20 to 16) AWG and 2 x (18 to 14) AWG respectively. The spring-cage or screw terminals (depending on variant) are sized for daisy-chaining through the auxiliary block. The mirror contact feature per IEC 60947-4-1 is confirmed for this block when used with 3RT2 contactors — meaning the NC contact cannot be held closed by welded main contacts, a safety requirement for feedback circuits in motor starters. The substance prohibition date of 10/01/2009 indicates RoHS compliance from that date forward.","metaTitle":"Siemens 3RH2916-1DA11 SIRIUS Auxiliary Switch, 10 mm wide, s","metaDescription":"Siemens SIRIUS 3RH2916-1DA11 auxiliary switch for S00 contactors. 1 NO + 0 NC, snap-on mounting, 10 mm wide.
