It carries a 6 A rating at 24 V and a 10 A rated value at the same voltage, with a contact reliability of one faulty switching per 100 million operations at 17 V, 1 mA. This auxiliary switch delivers 6 A at 24 V and 230 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, 3 A at 400 V, and 1 A at 690 V in AC-15 duty. The rated values at the same voltages are higher: 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, and 0.26 A at 600 V. The AC-15 rating at 690 V is 1 A, which covers the standard control-circuit voltage for many 400 V motor starters. Snap-on mounting directly onto the 3RH2140/3RH2440 auxiliary switch block — no tools needed. The S00 contactor size means it fits the smallest Siemens contactor frame. Wiring accepts 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) with ferruled ends; AWG equivalents are 2x (20 to 16) and 2x (18 to 14). Depth is 43.7 mm, width 36 mm, height 37.5 mm — the panel cutout and enclosure depth need to accommodate this, especially if the contactor is already mounted deep in the cabinet.","metaTitle":"Siemens 3RH2911-1GA04 SIRIUS Auxiliary Switch, 6 A at 24 V,","metaDescription":"Siemens 3RH2911-1GA04 SIRIUS auxiliary switch, snap-on for S00 contactors.
