It snaps onto a 35 mm DIN rail and connects via screw-type terminals, accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with core-end processing. Rated at 10 A maximum, the switch block delivers 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, and 3 A at 400 V. For DC-12/DC-13 duty, it handles 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. This part is a phased-out product. The official successor is the SIRIUS 3RH2 series. For BOM lines specifying the 3RH1911-1GA13-ZW96, the 3RH2 is the direct drop-in replacement from Siemens, sharing the same footprint and auxiliary contact function. Dimensions are 41.5 mm deep, 36.5 mm wide, and 37.5 mm high, so it adds minimal depth to the assembly. ## Electrical and Mechanical Durability","metaTitle":"Siemens 3RH1911-1GA13-ZW96 Auxiliary Switch Block, 10 A, 1 N","metaDescription":"Siemens SIRIUS auxiliary switch block 3RH1911-1GA13-ZW96, 1 NO + 3 NC, 10 A, screw terminals, snap-on mounting.
