The Siemens 3RH2911-1XA22-0MA0-Z W96 is a front-mounted auxiliary switch block for the 3RT2 contactor and 3RH2 contactor relay families. It carries 2 normally-open and 2 normally-closed contacts, wired via screw terminals, with the current path sequenced as 1 NO, 1 NC, 1 NC, 1 NO across terminals 53/54, 61/62, 71/72, and 83/84.
Snaps onto the front of the contactor or relay — no extra DIN rail space needed, no wiring harness change. The screw terminals accept standard ferrule or solid conductors; strip length and torque follow the contactor's own terminal spec. On a crowded panel, this keeps the auxiliary contacts within the device footprint rather than adding a separate terminal block row.
