Auxiliary switch block, side, 1 NO + 1 Oe, current path 1 Oe, 1 NO, for motor contactors, size S0-S3 screw connection R: 31 / 32, 43 / 44, L: 51 / 52, 63 / 64, SIRIUS 3RH29 auxiliary switch for extending the auxiliary contacts in the control circuit. The 3RH29 auxiliary switches that can be mounted on the side can be mounted on the 3RT2 contactors without tools, regardless of the size. The 3RH19/3RH29 auxiliary switch blocks are available as front-mounted or side-mounted versions, with up to four instantaneous switching or up to two leading switching NO and NC contacts. The auxiliary switches can be designed as positively guided contact elements in 3RH contactor relays or as mirror contacts in 3RT contactors. They are available with screw connections and spring-loaded connections. Simple, efficient, always up-to-date - the SIRIUS modular system.
