Description

Auxiliary contactor, 7 NO + 1 NC, 24 V DC, size S00, spring-loaded connector, auxiliary switch unlockable SIRIUS 3RH2 auxiliary relay for switching the control signals in the control circuit.The SIRIUS 3RH2 contactor relays have standard connection designations and reliable and time-saving connection technology. The simultaneous switching of several auxiliary circuits is possible through output multiplication. All contacts are also available as SUVA variants with positive guidance for safety applications. The auxiliary contactors are climate-proof, have a high contact reliability and are suitable for worldwide use with the corresponding approvals (e.g. IEC AND UL/CSA).They are available in AC or DC operation and are available with screw or spring-type tension technology. The basic version of the auxiliary contactor is 4 pole and can be expanded to 8 pole by snap-on auxiliary switch.The extensive accessories of 3RT2 contactors for sizes S00 to S3 can also be used for 3RH2 contactor relays.3RH2 contactor relays replace the tried and tested 3RH1 series.Simple, efficient, always up-to-date - the SIRIUS modular system.
