Product details

Siemens 3RT6016-1KB42 — SIRIUS coupling contactor, size S00

Rated for AC-3 duty up to 690 V, it delivers 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V — all at 60 °C ambient. The 24 VDC coil draws 6 A at rated value; a built-in suppressor diode handles the inductive kickback, so verify free-wheel diode polarity before energizing. Main and auxiliary circuits use screw-type terminals, accepting 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm² solid or stranded. Pollution degree 3 rating suits industrial environments with conductive contamination.

Snap onto 35 mm DIN rail per DIN EN 50022; the mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward. Side-by-side mounting is supported — no mandatory spacing gaps, so fill factor is tight. The S00 footprint matches other SIRIUS S00 contactors and overload relays for a consistent panel layout.

Frequently asked questions

What is 3RT6016-1KB42's listed depth (73 mm) on this component line?

The depth is 73 mm per the spec table.

What is 3RT6016-1KB42's listed width (45 mm) on this component line?

The width is 45 mm per the spec table.

Will 3RT6016-1KB42 drop into a panel that was specified around 3RT6017-1KF42 without rewiring?

Both are S00 size with the same 45 mm width and DIN rail snap-on mounting, so the mechanical fit is identical. However, the coil voltage differs — the 3RT6016-1KB42 uses 24 VDC, while the 3RT6017-1KF42 typically uses a higher AC coil. Rewiring the control circuit may be required if the panel's coil supply does not match 24 VDC.
