Coupling auxiliary contactor, 2 NO + 2 NC DC 72 V, 0.7 ... 1.25* US, with integrated suppressor diode, size S00, spring-loaded connection suitable for PLC outputs. Coupling auxiliary contactor SIRIUS 3RH2 for switching the control signals in the control circuit with direct connection option to electronic controls. The coupling auxiliary contactors SIRIUS 3RH2 have standard-compliant connection designations and a reliable and time-saving connection technology. The simultaneous switching of several auxiliary circuits is possible by duplicating the outputs. The contacts are also available as SUVA variants with positive guidance for safety applications. The coupling contactors are climate-resistant, have a high level of contact reliability and are suitable for worldwide use thanks to the relevant 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 extensive accessories for the 3RT2 contactors for sizes S00 to S3 can also be used for the 3RH2 coupling contactors. The 3RH2 coupling contactors replace the proven 3RH1 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
