It is rated for a maximum of 10 A, with specific switching capacities depending on the control voltage: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. The AC-15 rating at 690 V is 1 A, which governs its use in solenoid and contactor coil circuits at higher voltages. ## Contact reliability and service life ## Panel integration Snap-on mounting to the contactor or relay front face — no tools needed. The block occupies 36 mm width, 41.5 mm height, and 47.7 mm depth, adding minimal footprint to the existing device. The spring-loaded terminals reduce wiring time compared to screw terminals; strip length is 8 mm for a clean connection.","metaTitle":"Siemens SIRIUS 3RH2911-2HA02-ZW97 Auxiliary Switch, 2 NC, 10","metaDescription":"Siemens SIRIUS 3RH2911-2HA02-ZW97 auxiliary switch, 2 NC contacts, 10 A max, spring-loaded terminals, snap-on for 3RT2/3RH2 contactors.
