The 3RH1921-2TA11-Z X92 is an auxiliary switch block that adds one normally-open and one normally-closed contact to a motor contactor. It mounts per EN 50005, which means it clips onto the contactor's front or side without extra hardware — a standard interface across the SIRIUS family.
RoHS compliant since July 2006, with REACH candidate-list information available on request. Packaged in multi-unit quantities of 46 pieces per carton, individual unit dimensions are 73 x 70 x 15 mm — small enough to keep a handful on the shelf for line-down spares without eating up bin space.
Integration notes
Mounts onto SIRIUS contactors per EN 50005. The block sits flush against the contactor body, adding no width beyond the contactor envelope. Spring-loaded terminals are rated for the contactor's auxiliary circuit; no separate fuse needed for the signal side. Wire the NO and NC as dry contacts — the block doesn't draw coil current, it just mirrors the contactor's armature position.
