Product details

The Siemens 3RK1315-6KS41-3AA5 is a SIRIUS reversing motor starter in a fully enclosed IP65 housing, rated for 0.75 kW at 400 V and 0.7 hp at 460/480 V. It is a reversing starter, meaning it can switch a motor in both forward and reverse directions from a single unit — useful for conveyor reversals, gate drives, or any bidirectional load.

This is a standalone enclosure-rated starter — not a DIN-rail module. It mounts via screw fixing in any orientation (vertical, horizontal, flat), though horizontal is recommended. Main power connects via a HAN Q4/2 plug per ISO 23570; the AS-Interface fieldbus and 24 VDC supply come through an M12 connector. Four digital inputs are available on-board.

The 24 VDC supply range is 20.4 to 28.8 V, with an absolute maximum of 31.6 V — stay within that window. Vibration resistance is 7 mm / 2g; shock resistance is 12g for 11 ms — suitable for machine-mounted duty on conveyors or packaging equipment.

Frequently asked questions

What are the physical dimensions of this starter?

The enclosure measures 294 mm wide, 215 mm high, and 159 mm deep. It mounts via screw fixing.

What fieldbus protocol does it support?

It supports AS-Interface. It does not support PROFIBUS DP or PROFINET.

What is the trip class and what does it mean?

It is CLASS 10, meaning the overload relay will trip within 10 seconds at locked-rotor current. This is the standard class for general-purpose induction motors and prevents winding damage during a stall.

Can this starter be used in washdown environments?

Yes, the IP65 rating means it is dust-tight and protected against water jets, suitable for food processing or other washdown areas.
