What it is and where it fits
The 3RH2911-2HA31-Z W97 is a front-mounted auxiliary switch block from Siemens, configured 3 normally open + 1 normally closed, with spring-loaded terminals. It mounts directly onto 3RT2 contactors and 3RH2 contactor relays, adding auxiliary contact capacity without extra panel wiring. The spring-loaded terminal accepts solid or ferruled stranded conductors — no screw torque check needed during commissioning.
