Auxiliary contactor, 3 NO + 1 NC, DC 60 V, size S00, screw connection SIRIUS 3RH2 auxiliary contactor for switching the control signals in the control circuit. The SIRIUS 3RH2 auxiliary contactors have standard-compliant connection designations and a reliable and time-saving connection technology. The simultaneous switching of several auxiliary circuits is possible by multiplying the outputs. All contacts are also available as SUVA versions with positive guidance for safety applications. The auxiliary contactors are climate-resistant, have a high level of contact reliability and are suitable for worldwide use thanks to the corresponding approvals (e.g. IEC and UL/CSA). They are available in AC or DC operation and are available with screw or spring-loaded technology. The basic version of the contactor relays is 4-pole and can be extended to 8 poles using snap-on auxiliary switches.The extensive accessories for the 3RT2 contactors for sizes S00 to S3 can also be used for the 3RH2 contactor relays.The 3RH2 contactor relays replace the tried and tested 3RH1 series.Simple, efficient, always up to date - the SIRIUS modular system.
