Product details

Auxiliary relay, 2 S + 2 Ö, AC 120 V, 50 / 60 Hz size S00, screw 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 the simultaneous switching of multiple auxiliary circuits. All contacts are available with forced guidance for safety applications, also in SUVA variants. The auxiliary relays are climate-resistant, have high contact reliability, and are suitable for worldwide use with appropriate approvals (e.g., IEC and UL/CSA). They are available in AC or DC operation and come with screw or spring connection technology. The basic version of the auxiliary relays is 4-pole and can be expanded to up 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 3RH1 series. Simple, efficient, always up to date - the SIRIUS modular system.
