auxiliary switch, solid-state compatible, lateral, 1 NO + 1 NC, on the left: 51/52, 63/64, current path: 1 NC, 1 NO, on the right: 33/34, 41/42, current path: 1 NO, 1 NC, spring-loaded terminal, for contactors 3RT2 and contactor relays 3RH2 auxiliary switch SIRIUS 3RH29 for the expansion of auxiliary contacts in the control circuit.3RH29 auxiliary switches can be laterally mounted onto 3RT2 contactors without tools regardless of their 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 relays or 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.
