auxiliary switch, on the front, 4 NC, 51/52, 61/62, 71/72, 81/82, current path: 1 NC, 1 NC, 1 NC, 1 NC, screw terminal, physically coded, only with contactor relays 3RH2140 and 3RH2440 combinable (according to EN 50011) auxiliary switch SIRIUS 3RH29 for the expansion of auxiliary contacts in the control circuit. The front-mounted 3RH29 auxiliary switches can be installed on 3RT2 contactors and 3RH2 contactor relays without the need for tools, regardless of size. The 3RH19/3RH29 auxiliary switches are available as versions for front or lateral mounting, with up to four instantaneous contacts or up to two leading NO and NC contacts. The auxiliary switches can be designed as positively driven contacts in 3RH contactor relaysor also as mirror contacts in the case of 3RT power contactors. All of them are available with screw terminal and spring-type terminal. Simple, efficient and always up to date - SIRIUS modular system.

Contactor relay, 4 NO, 24 V AC, 50 / 60 Hz, Size S00, screw terminal Auxiliary contactor SIRIUS 3RH2 for switching the control signals in the control circuit. The SIRIUS 3RH2 contactor relays have standard-compliant terminal designations and a reliable and time-saving connection technology. Thanks to the multiplication of outputs, simultaneous switching of several auxiliary circuits is possible. All contacts are available with positively driven operation for safety applications as well as SUVA versions. The contactor relays are climate-resistant, have a high contact reliability and are suitable for use worldwide thanks to the corresponding approvals (e.g. IEC and UL/CSA). They are available with AC or DC operation and with screw or spring-loaded terminals. The basic version of the contactor relays is a 4-pole design which can be extended up to 8 poles by means of snap-on auxiliary switches. The extensive range of accessories for the 3RT2 contactors in sizes S00 to S3 can also be used for the 3RH2 contactor relays. The 3RH2 contactor relays replace the well-proven 3RH1 series.Simple, efficient and always up to date - SIRIUS modular system.
