Description

First lateral auxiliary switch 2 NC contacts, screw terminals, for SIRIUS 3RH19 3RT1 contactor switches for expansion of the auxiliary contacts in the control circuit.
This 3RH19 auxiliary switch can be mounted on the 3RT1 contactors of sizes S0-S12 without the need for tools.
The 3RH19/3RH29 auxiliary switches are available as front or side mounted versions, with up to four instantaneous switching or up to two leading-switching locks and NC contacts. The auxiliary switches can be designed as positively-driven contact elements in 3RH contactor relays or as mirror contacts in 3RT power contactors. They are available throughout with screw terminals and spring-type terminals.
Simple, efficient, always up-to-date - the SIRIUS modular system.
