The block is 41.5 mm deep, 28.5 mm wide, and 37.5 mm tall, fitting the compact S00 footprint. The 1 NO contact is rated for AC-15 duty at 690 V (1 A) and carries a mechanical service life of 10 million switching cycles. The snap-on fastening method integrates directly onto the S00 contactor without additional hardware.","metaTitle":"Siemens 3RH1911-1AA10 Auxiliary Switch Block, 1 NO, S00, 10","metaDescription":"Siemens SIRIUS 3RH1911-1AA10 auxiliary switch block, 1 NO contact, screw terminals, snap-on for S00 contactors.
