It mounts on Size S00 contactor relays and contactors used for switching motor loads, following the DIN EN50005 actuation standard. The block adds four auxiliary contacts to the base contactor — two NO, two NC — for feedback, interlocking, or control-circuit extension. Screw termination suits panel builds where ring-tongue or fork terminals are preferred over spring-cage. ## Integration note Size S00 is the smallest frame in the Siemens 3RH2 contactor relay family. The auxiliary block clips onto the front of the relay without increasing the panel footprint — no extra DIN-rail space needed. Screw terminals accept 1 x 0.5–2.5 mm² or 2 x 0.5–1.5 mm² conductors.","metaTitle":"3RH1911-1FC22-ZW95 Auxiliary Switch Block, 2NO+2NC, Screw, S","metaDescription":"Siemens 3RH1911-1FC22-ZW95 auxiliary switch block, 2NO+2NC contacts, screw connection, Size S00 for contactor relays.
