SIRIUS 3RH2 coupling auxiliary relay for switching control signals in the control circuit with direct connection possibility to electronic controls. The SIRIUS 3RH2 coupling auxiliary relays have standardized connection designations and a reliable, time-saving connection technology. Output multiplication allows simultaneous switching of multiple auxiliary circuits. The contacts are available with forced guidance for safety applications as SUVA variants. The coupling auxiliary relays are climate-resistant, have high contact reliability, and are suitable for global use due to corresponding approvals (e.g., IEC and UL/CSA). They are available for AC or DC actuation and come with screw or spring connection technology. The extensive accessories of the 3RT2 relays for sizes S00 to S3 can also be used for the 3RH2 coupling auxiliary relays. The 3RH2 coupling auxiliary relays replace the proven series 3RH1. Simple, efficient, always up to date - the SIRIUS modular system. EAN: 4011209848726.
