Rated impulse withstand voltage is 6 kV, which covers most industrial mains transient environments without external suppression.","metaTitle":"Siemens 3RH6140-1AQ00 SIRIUS Contactor Relay, 4 NO, S00","metaDescription":"Siemens 3RH6140-1AQ00 SIRIUS contactor relay, size S00, 4 NO auxiliary contacts, AC coil, 45 mm wide.
