Product details

Direct motor starter for washdown zones

The Siemens SIRIUS 3RK1395-6KS41-2AD3 is a direct motor starter rated for 0.75 kW at 400 V AC, with a selectable trip class of 5, 10, 15, or 20. The IP65 enclosure means the unit withstands hose-down cleaning in food-and-beverage or chemical processing lines — the housing and the HAN Q4/2 main-circuit plug (per ISO 23570) keep water out of the power connections. Supply voltage is 24 V DC nominal, with a tolerance band of 20.4 to 28.8 V DC, so it holds the unit on the grid through a lightly loaded 24 V bus.

Fastening is screw fixing; the unit can be mounted vertically, horizontally, or flat, though the manufacturer recommends horizontal orientation. Dimensions are 294 mm wide by 215 mm high by 148 mm deep — that footprint is sized for a dedicated enclosure, not a crowded DIN-rail cabinet. Four digital inputs and two digital outputs are onboard for local control signals; the main circuit connects via the HAN Q4/2 plug, so the power wiring is a pre-terminated harness, not field-stripped cable.

Frequently asked questions

How do I get current pricing and availability for 3RK1395-6KS41-2AD3?

Submit an RFQ against this order code. The unit is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.

What is 3RK1395-6KS41-2AD3's listed depth and width?

Depth is 148 mm, width is 294 mm, height is 215 mm. These dimensions are for the enclosure body; the HAN Q4/2 plug adds depth beyond the face.

What trip classes does this starter support?

The trip class is selectable among CLASS 5, 10, 15, and 20. This lets you match the overload curve to the motor's starting profile — a high-inertia load gets a longer acceleration window (CLASS 20), while a pump that starts unloaded can use CLASS 10.
