What It Is and Where It Fits
The Siemens 3RT2016-1AM12 is a SIRIUS power contactor in the compact S00 frame size, designed for switching motor loads and resistive loads in industrial control panels. It occupies a 45 mm wide DIN-rail footprint (screw and snap-on mounting per DIN EN 60715), with a depth of 73 mm and height of 58 mm — sized for high-density panel layouts where every millimeter of rail space counts.
Mounting and Wiring Flexibility
Mounting position is flexible: the contactor can be rotated ±180° on a vertical surface and tilted forward/backward by ±22.5°, which helps when routing wires in tight enclosures. The screw-type coil terminals accept solid or stranded wire from 0.5 to 4 mm² (single conductor) or 2x (0.5 to 1.5 mm²) with ferrules. Clearance spacing: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm to the side — plan your DIN-rail layout with these clearances to avoid heat buildup and arcing interference.
