Description

Auxiliary switch on front, 2 NO + 2 NC current path 1 NO, 1 NO, 1 NC, 1 NC for 3RH2 and 3RT2 screw terminals .3/.4, .3/.4, .1/.2, .1/.2 SIRIUS 3RH29 auxiliary switches for extending the auxiliary contacts in the control circuit.
The 3RH29 auxiliary switches on the front can be mounted on the 3RT2 contactors and 3RH2 contactor relays regardless of size 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.
