It gives you one normally-open and three normally-closed auxiliary contacts in a single snap-on module that clips directly onto the contactor front without extra wiring space on the DIN rail. Rated for 10 A maximum, with a 10 A continuous rating at 24 V, it handles typical control-circuit loads on the panel side. The AC-15 rating at 690 V is 1 A, which covers inductive solenoid and contactor coil switching at higher voltages. Spring-loaded terminals accept 2x (0.5 to 1.5 mm²) with ferrule or 2x (0.5 to 2.5 mm²) solid — no screwdriver needed for termination, which speeds up panel wiring and eliminates torque-check steps during commissioning. ## Switching capability across voltages This block is rated for DC switching across a wide voltage range: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, 3 A at 400 V. The AC rated values differ slightly: 10 A at 24 V, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V. For AC-15 inductive loads at 690 V, it carries 1 A. Dimensions: 36 mm wide, 41.5 mm high, 47.7 mm deep — it adds minimal depth to the contactor front. Snap-on mounting means no tools for attachment, and the IP20 front protection keeps fingers away from live terminals inside the enclosure.","metaTitle":"Siemens 3RH2911-2HA13 SIRIUS Auxiliary Switch, 1NO+3NC, 10A,","metaDescription":"Siemens SIRIUS 3RH2911-2HA13 auxiliary switch block for 3RT2/3RH2 contactors. 1 NO + 3 NC, 10 A rated, spring-loaded terminals, snap-on mounting.
