Description

Front-sided auxiliary switch, 1 NO leading, screw connection, for 3RT1 auxiliary switch SIRIUS 3RH19 for extending the auxiliary contacts in the control circuit.This auxiliary switch 3RH19 can be mounted without tools on the 3RT1 contactors and 3RH1 contactor relays of sizes S0-S12.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.
