Auxiliary switch block for 3RT2/3RH2 — four NC, front-mounted
The Siemens 3RH2911-1XA04-0MA0-Z W98 is a four-pole normally-closed auxiliary switch block that mounts on the front of 3RT2 contactors and 3RH2 contactor relays. Each of the four current paths is a single NC contact — terminals 51/52, 61/62, 71/72, 81/82 — wired via screw terminals. The front-mount position means it adds status feedback or interlock logic without increasing the panel depth behind the contactor.
Compliance and packaging
RoHS compliant since 01-10-09; REACH Article 33 information is available on request. The unit ships as a single piece (packaging quantity 1), but the description notes multi-unit packaging — pack of 60 units — so the order code covers a bulk carton. Dimensions are 57.00 x 50.00 x 42.00 mm, which fits the standard front-mount footprint for the 3RT2/3RH2 family.
