Railway coupling auxiliary contactor, 2 NO + 2 Oe, DC 24 V, 0.7 ... 1.25* US, with integrated varistor, size S00, spring-loaded connection SIRIUS 3RH2 coupling auxiliary contactor for switching the control signals in the control circuit with direct connection option to electronic controls. The SIRIUS 3RH2 coupling auxiliary contactors have standard-compliant connection designations and a reliable and time-saving connection technology. Output multiplication makes it possible to switch several auxiliary circuits at the same time. The contacts are also available as SUVA variants with positive guidance for safety applications. The coupling auxiliary contactors are climate-resistant, have a high 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 extensive accessories for the 3RT2 contactors for sizes S00 to S3 can also be used for the 3RH2 coupling auxiliary contactors. The 3RH2 coupling auxiliary contactors replace the proven 3RH1 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
