It carries 1 NO + 1 NC auxiliary contact and connects via screw-type terminals. ## Lifecycle and replacement This part is flagged as a phased-out product. The official Siemens successor is the SIRIUS 3RT2926-2PR11, which is the preferred replacement type. ## Fit and wiring The block snaps onto the front of a 3RT1.2 contactor — no tools, no extra DIN rail space. The screw-type terminals accept the same wire sizes as the contactor's auxiliary terminals, so you can land 1.5 mm² or 2.5 mm² stranded without changing your wiring habits. ## Short-circuit protection The auxiliary switch requires a gG 10 A fuse with a short-circuit current rating of 1 kA per IEC 60947-5-1. If you are using a miniature circuit breaker instead, the spec calls for a C-characteristic 6 A breaker at 230 V.","metaTitle":"Siemens 3RT1926-2PR11 SIRIUS Pneumatic Delay Block, Off-Dela","metaDescription":"Siemens SIRIUS 3RT1926-2PR11 pneumatic off-delay block, 1-60s adjustable, 1NO+1NC, screw terminals.
