Siemens 3RH21221BF40auxiliary contactor, 2 NO+2 NC, DC 110 V, size S00, screw terminal SIRIUS 3RH2 auxiliary contactor for switching control signals in the control circuit.\ nThe SIRIUS 3RH2 contactor relays feature standard-compliant terminal designations and fast, reliable connection technology. Thanks to the multiplication of the outputs, simultaneous switching of multiple auxiliary circuits is possible. All contacts can be supplied with forced guidance for safety applications also as an SUVA variant. The auxiliary contactors are tropicalised, have high contact safety and are suitable for use worldwide thanks to the corresponding approvals (e.g. IEC and UL/CSA).\nThey can be supplied with AC or DC control and are available with screw or spring terminals. The basic design of the contactor auxiliaries is 4-pole and can be expanded to 8-pole with snap-in auxiliary contact blocks.\nThe numerous accessories for the 3RT2 contactors in frame sizes S00 to S3 can also be used for the contactors 3RH2 auxiliary contactors.\nThe 3RH2 auxiliary contactors replace the proven 3RH1 series.\nSimple, efficient, always up-to-date - the SIRIUS modular system.
