The contacts are rated for switching control circuits and are terminated with spring-loaded (cage-clamp) terminals, which speeds wiring and resists loosening under vibration compared to screw terminals. RoHS compliance is confirmed from October 2009 onward, and the part carries no export control restrictions (AL: N / ECCN: N), simplifying cross-border procurement. ## Contact Configuration and Wiring The contact arrangement is 3 NO + 1 NC, with the NC contact on the first pole position (current path identified as 1 NC, 1 NO, 1 NO, 1 NO). This is a common pattern for signaling a contactor's energized state while providing one break contact for safety interlocks.","metaTitle":"Siemens 3RH2911-2HA31-Z X95 Auxiliary Switch, 3 NO + 1 NC","metaDescription":"Siemens 3RH2911-2HA31-Z X95 auxiliary switch block for 3RT2/3RH2 contactors. 3 NO + 1 NC, spring-loaded terminals, active production.
