If your panel layout was designed around a standard 55 mm contactor footprint (like the SIRIUS S2 frame), this module is over twice the width, so it won't drop into the same slot without re-railing. The 'without supply line connection' variant means it takes its feed from an adjacent module — verify the busbar or jumper scheme in your existing ET200S string before committing the BOM line. ## Deployment context It's rated IP20 on the front, so it belongs inside a control cabinet, not in a washdown or outdoor zone. If you're retrofitting into an existing ET200S station, check the slot assignment: the High Feature Reversing starter requires this specific terminal module to handle the reversing contactor wiring; a standard ET200S terminal module won't carry the same internal bus routing.","metaTitle":"Siemens 3RK1903-0AL10 Terminal Module, ET200S Reversing Star","metaDescription":"Siemens 3RK1903-0AL10 terminal module for ET200S High Feature Reversing starter, no supply line connection.
