For DC-13 loads the ratings shift: 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-12 maximum continuous current is 10 A. Snaps onto the front of a 3RH2140/3RH2440 auxiliary switch block or directly onto an S00 contactor relay. Occupies a 36.5 mm wide slot, 41.5 mm deep, 37.5 mm tall — fits standard DIN-rail enclosures without overhang. Wiring accepts 2x (0.5... 1.5 mm²) solid or finely stranded with ferrule, or 2x (0.75... 2.5 mm²) — covers the common panel-building range. AWG equivalents: 2x (20... 16) and 2x (18... 14). Front protection class is IP20; the switch block is intended for inside-enclosure use where the front remains touch-safe. ## Contact reliability and safety compliance The auxiliary contacts are mirror contacts per IEC 60947-4-1 when used with 3RT1 contactors, meaning the NO contacts reflect the main contact position for safety circuit integrity.","metaTitle":"Siemens 3RH1911-1GA40-ZW96 SIRIUS Auxiliary Switch, 4 NO con","metaDescription":"Siemens 3RH1911-1GA40-ZW96 SIRIUS auxiliary switch, 4 NO contacts, snap-on mounting for S00 contactors.
