This part distributes the potential group supply from a single infeed point to multiple ET200S remote I/O stations. The 30 mm width matches the standard ET200S module footprint on a 35 mm DIN rail per EN 50022, and the left-side infeed orientation means it occupies the first slot in the potential group — plan the rail layout so the feed terminals are accessible for the incoming 24 V DC supply cable. Because the part forwards the potential to up to six downstream ET200S stations, the total current draw of those six stations' loads must stay within the rating of the upstream power supply and the infeed terminals on this distributor — no built-in fuse, so the branch protection is external. Substance prohibitance date is 05/01/2012.","metaTitle":"Siemens 3RK1903-3AE10 TM-PFX30 Potential Group Distributor,","metaDescription":"Siemens SIRIUS 3RK1903-3AE10 TM-PFX30 potential group distributor, infeed from left, forwarding U1 to 6 external ET200S stations.
