The single digital input handles the start/stop command locally. ## IP55 enclosure and mounting flexibility IP55 means the housing is dust-protected and can handle water jets from any direction — suitable for washdown areas in food processing or outdoor cabinets, but not for submersion or high-pressure spray. The unit mounts on a vertical surface with ±180° rotation possible and can be tilted forward or backward by ±22.5° on that same surface, so you can orient it to fit existing gland plates or cable entries. Dimensions are 145 mm deep, 182 mm wide, 220 mm tall — check the panel depth before committing; the 182 mm width may require a wider-than-standard DIN-rail backplate if you're retrofitting into a tight enclosure. ## Active lifecycle — no obsolescence risk for BOM planning Substance prohibitance date is 05/01/2012 — the part complies with RoHS and REACH substance restrictions as of that date. For volume purchases or MRO spares, submit an RFQ with the target quantity and delivery window.","metaTitle":"Siemens 3RK4353-3PR58-0BA0 SIRIUS Motor Starter, 12 A AC-3","metaDescription":"Siemens 3RK4353-3PR58-0BA0 SIRIUS motor starter, 12 A at 400 V AC-3, Trip Class 10, IP55.
