Auxiliary relay for rail applications, 2 S + 1 Ö, DC 110 V, 0.7 ... 1.25* US, with integrated varistor, 3-pole, size S00, spring connection. SIRIUS 3RH2 auxiliary relay for switching control signals in the control circuit. The SIRIUS 3RH2 auxiliary relays have standardized connection designations and a reliable, time-saving connection technology. Output duplication allows for simultaneous switching of multiple auxiliary circuits. All contacts are available with forced guidance for safety applications, also as SUVA variants. The auxiliary relays are climate-resistant, have high contact reliability, and are suitable for worldwide 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 basic version of the auxiliary relays is 4-pole and can be expanded to 8 poles with snap-on auxiliary switches. The extensive accessories of the 3RT2 relays for sizes S00 to S3 can also be used for the 3RH2 auxiliary relays. The 3RH2 auxiliary relays replace the proven series 3RH1. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
