This block snaps onto the contactor or relay — no tools needed for the mount, and it fits the standard DIN-rail footprint. The screw terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with core-end processing, or the AWG equivalents 2x (20 to 16) and 2x (18 to 14). Front protection is IP20, so it's fine inside an enclosure but not for washdown areas. The block is 36.5 mm wide, 41.5 mm deep, and 37.5 mm high — it won't eat up much rail space.","metaTitle":"Siemens 3RH1911-1HA01-ZW96 Auxiliary Switch Block, 10 A, SIR","metaDescription":"Siemens SIRIUS 3RH1911-1HA01-ZW96 auxiliary switch block, 10 A, 1 NO + 1 NC, screw terminals, snap-on mounting.
