Description

Auxiliary switch on the front, 2 S power track 1 S, 1 S Connection from the bottom for 3RH2 and 3RT2 screw connections 73/74, 83/84 auxiliary switches SIRIUS 3RH29 for extending the auxiliary contacts in the control circuit.The 3RH29 front-side auxiliary switches can be mounted on the 3RT2 contactors and 3RH2 contactor relays without any size tools.The 3RH19/3RH29 auxiliary switches are available as front-side or side-mountable variants, with up to four instantaneous switching or up to two leading-edge closing contacts and NC contacts. The auxiliary switches can be designed as positively-driven contact elements in 3RH auxiliary contactors or as mirror contacts in 3RT power contactors. They are available throughout with screw connection and spring connection.Simple, efficient, always up-to-date - the SIRIUS modular system.
