The ring terminal lug connection means wiring lands on a screw-type ring terminal, not a spring cage — expect a stripped ring or fork terminal on each pole. Rated operational currents span the control-voltage range: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V and 250 V, and 3 A at 400 V (–). The AC-15 rating at 690 V is 1 A, and the AC-12 maximum is 10 A — the AC-12 figure governs resistive loads; Snap-on mounting onto the DIN-rail-mounted contactor relay — no screws, no tools for the attachment. The block itself measures 36 mm wide by 43.7 mm deep by 37.5 mm high (–). That 36 mm width is a standard 2-pole module pitch, so it occupies two 18 mm slots on the rail. Front protection is IP00, meaning the contacts are exposed — the panel enclosure provides the environmental seal. Substance prohibitance date is 10/01/2009, aligning with RoHS and REACH compliance timelines. The part carries no mirror-contact function per IEC 60947-4-1, so it is not suitable for safety-related feedback that requires a mechanically linked NC mirror contact. No leading or lagging contact timing — all contacts are instantaneous.","metaTitle":"Siemens 3RH2911-4GA22 SIRIUS Auxiliary Switch, 2 NO contacts","metaDescription":"Siemens SIRIUS 3RH2911-4GA22 auxiliary switch for S00 contactors. 2 NO contacts, snap-on mount, ring terminal connection.
