Siemens 3RT6016-1KB42 — SIRIUS coupling contactor, size S00
The Siemens 3RT6016-1KB42 is a SIRIUS coupling contactor in size S00, designed for switching motor loads and resistive circuits in control panels. It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 50022, with side-by-side mounting permitted for dense panel layouts. 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.
Mounting and integration
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. Dimensions: 45 mm wide, 57.5 mm high, 73 mm deep. The S00 footprint matches other SIRIUS S00 contactors and overload relays for a consistent panel layout.
