The switching capacity varies by voltage: at 24 V it is rated 10 A (AC-15), at 230 V it is 6 A, and at 690 V AC-15 it drops to 1 A. For DC loads, the ratings are 6 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These are the values that determine whether the block can handle your specific control load — match the voltage column to your circuit. The insulation rating is 690 V AC with pollution degree 3, and the rated surge voltage withstand is 6 kV. This means the block is suitable for 400 V line-to-line control panels without additional creepage concerns, and it passes the impulse voltage test typical for industrial environments. Dimensions are 36.5 mm wide, 37.5 mm high, and 41.5 mm deep — it occupies the S00 contactor footprint. The screw terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with ferrule processing, or 2x (20 to 16 AWG) or 2x (18 to 14 AWG) solid/stranded. Front protection class is IP20, so the block is intended for use inside a panel enclosure. Mechanical service life is 10 million switching cycles typical. The block is rated for use with contactor relays and power contactors in the SIRIUS family.","metaTitle":"Siemens 3RH1911-1FA31-ZW96 SIRIUS Auxiliary Switch Block, 10","metaDescription":"Siemens SIRIUS 3RH1911-1FA31-ZW96 auxiliary switch block, 3 NO + 1 NC, 10 A rated, snap-on mounting.
