It is designed for use with contactor relays and power contactors in the SIRIUS family, snap-mounted onto a DIN rail within a control panel. The contact ratings are specified per voltage: 10 A at 24 V, 6 A at 24 V (separate entry), 6 A at 60 V, 1 A at 110 V, 6 A at 125 V, 0.3 A at 220 V, 6 A at 230 V, 6 A at 250 V, and 3 A at 400 V. For AC-15 duty at 690 V, the rated operational current is 1 A. Mechanical service life is rated at 10,000,000 switching cycles typical, with contact reliability specified as 1 faulty switching per 100 million operations at 17 V and 1 mA. This part is a phased-out product. The manufacturer's official successor is the SIRIUS 3RH2 series. For BOM lines that reference this order code, the 3RH2 is the drop-in replacement path to evaluate. ## Integration Notes Dimensions: 36.5 mm wide, 41.5 mm deep, 37.5 mm tall. Accepts screw-type terminations for 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid/stranded with core-end processing, or 2x (20 to 16) and 2x (18 to 14) AWG. The 22 E footprint per EN 50012 fits standard contactor relay slots.","metaTitle":"Siemens 3RH1911-1HA12-ZW96 Auxiliary Switch Block, 10 A, SIR","metaDescription":"Siemens SIRIUS 3RH1911-1HA12-ZW96 auxiliary switch block, 22 E, 1 NO + 2 NC, screw terminals, snap-on mounting.
