The 3RH19 auxiliary switch is the first side-mounted auxiliary switch with 1 normally closed and 1 normally open contact, encapsulated (suitable for electronics), with spring terminal connection, for contactors 3RT1. The SIRIUS 3RH19 auxiliary switch is used to expand the auxiliary contacts in the control circuit. This auxiliary switch can be mounted on 3RT1 contactors of sizes S0-S12 without tools. The 3RH19/3RH29 auxiliary switches are available as front or side-mounted variants, with up to four instantaneously switching normally closed or up to two early switching normally open contacts. The auxiliary switches can be designed as forcibly guided contact elements in auxiliary contactors 3RH or as mirror contacts in power contactors 3RT. They are available with both screw and spring terminal connections. Simple, efficient, always up to date - the SIRIUS system modular concept.
