Product details

12 A AC-3 motor switching — the rating that decides the load

The 3RK4353-3PR58-0BA0: It's a direct starter (no reversing or star-delta), controlled on-site via the MCU interface — no fieldbus, no PROFINET, no PROFIBUS. 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.

Frequently asked questions

What is the closest functional second-source for 3RK4353-3PR58-0BA0?

The part is a SIRIUS motor starter with a specific footprint and MCU control — a board spin or panel rework would be needed to substitute a different manufacturer's starter.
