Product details

SIRIUS direct starter, IP65, 5.5 kW

The Siemens 3RK1315-6LS41-0AA3 is a SIRIUS direct starter rated for 5.5 kW at 400 V and 7.5 hp at 460/480 V, with a Trip Class 10 thermal overload curve. It operates on a 24 V DC supply (20.4...28.8 V) and includes 4 digital inputs for local or remote control. The IP65 enclosure means it handles washdown environments — suitable for food-and-bev or light industrial lines where dust and hose-directed water are present.

Fastened by screw fixing, the unit measures 294 mm wide, 215 mm high, and 159 mm deep. Mounting position is flexible — vertical, horizontal, or flat — though horizontal is recommended. The main current circuit connects via a HAN Q4/2 plug per ISO 23570; device addressing uses an M12 plug. That's a panel footprint that fits a standard enclosure gland plate, but the 294 mm width means it takes up a full slot width on a DIN-rail backplate — plan the fill factor accordingly.

Frequently asked questions

How do I get current pricing and availability for 3RK1315-6LS41-0AA3?

Submit an RFQ against this order code. We source through independent distribution and confirm pricing and availability at quote time.

What is the IP rating and what does it mean for deployment?

IP65 means the enclosure is dust-tight and protected against low-pressure water jets from any direction. It's suited for washdown areas in food processing or outdoor cabinets where rain and dust are a concern.

What is the trip class and why does it matter?

Trip Class 10 means the overload relay will trip within 10 seconds at 7.2× the current setting. That's the standard for standard-duty induction motor starting — it allows the motor to accelerate without nuisance tripping but protects against prolonged overload.
