It provides one normally-open and two normally-closed contacts (1 NO + 2 NC) in a 22E footprint per EN 50012, with spring-type terminals for fast, vibration-resistant wiring. This block mounts directly onto compatible SIRIUS contactors, adding auxiliary switching capacity for control circuits, status feedback, or interlocking. This order code is marked as a phased-out product. The lifecycle stage is listed as current, meaning it is still being produced but is on the path to discontinuation. The official successor is the SIRIUS 3RH2 series. For a BOM line that needs a long-term supply guarantee, the 3RH2 is the drop-in replacement to qualify now. ## Integration note The 22E width matches the standard SIRIUS contactor mounting profile; the block clips onto the contactor front without additional DIN-rail space. Multi-unit packaging of 60 units suits panel shops running multiple builds.","metaTitle":"Siemens 3RH1911-2HA12-ZW98 Auxiliary Switch Block, 1 NO + 2","metaDescription":"Siemens 3RH1911-2HA12-ZW98 auxiliary switch block, 22E, 1 NO + 2 NC, EN 50012, spring-type terminal, 4-pole.
