It provides 2 normally-open and 2 normally-closed contacts, wired out to spring-loaded terminals that accept 2x (0.5... 1.5 mm²) with ferrule or 2x (0.5... 2.5 mm²) solid — no screw torque to check, no loosening from vibration. The snap-on mounting clips directly to the contactor front, adding no DIN-rail width. The insulation voltage is rated 690 V at pollution degree 3, so this switch block can live in the same panel as the main power contactor without forced separation. The AC-15 rating at 690 V is 1 A, meaning it can reliably switch solenoid valves and contactor coils at line voltage in industrial control circuits.","metaTitle":"Siemens 3RH2911-2HA22-ZW96 Auxiliary Switch, 2NO+2NC, Spring","metaDescription":"Siemens SIRIUS 3RH2911-2HA22-ZW96 front-mounted auxiliary switch for 3RT2/3RH2 contactors. 2 NO + 2 NC, spring-loaded terminals, IP20, 690 V insulation.
