IP55 means it handles dust and low-pressure water jets from any direction, so it can live on the machine frame rather than inside a sealed cabinet, but it is not rated for submersion or high-pressure washdown. Mounting is flexible: the starter can be rotated ±180° on a vertical surface and tilted forward or backward by ±22.5° on a vertical mount, which helps in tight enclosures or angled machine frames. ## Supply voltage and control inputs The power supply is AC only, rated 340-440 V operating voltage. The control coil accepts 184-253 V at 50 Hz or 196-253 V at 60 Hz — a wide tolerance that covers most European and North American industrial supplies without a tap change. Two digital inputs are built in for local start/stop or reversing commands — no fieldbus module needed for basic operation. There is no PROFINET, PROFIBUS, or AS-Interface protocol support on this variant; if you need network control, look at the bus-capable versions in the SIRIUS family.","metaTitle":"Siemens 3RK4353-3MR58-1BA0 SIRIUS Reversing Starter","metaDescription":"Siemens 3RK4353-3MR58-1BA0 SIRIUS reversing motor starter, rated 8 A at 400 V AC-3, CLASS 10 trip, IP55 enclosure.
