What it is and what it does
The Siemens 3RT2016-1AP62 is a SIRIUS power contactor in Size S00, designed for switching motor loads and resistive loads in industrial control panels. It carries a 24 VDC coil and includes an integrated auxiliary switch, which saves a separate auxiliary contact block for basic status feedback. Rated for AC-3 switching duty (motor starting) at 750 operations per hour, and up to 1 000 1/h for AC-1 resistive loads. The AC-4 (plugging/reversing) rate is lower at 250 1/h — a typical constraint for contactors this size when handling inching duty. The auxiliary contact set is rated for 10 A at 24 V, 3 A at 400 V, and down to 0.2 A at 440 V — enough for PLC digital inputs or small relay coils in most 24 VDC control circuits.
Mounting and integration
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width (three 15 mm modules) and 58 mm height fit standard panel layouts. Depth is 73 mm, which leaves room for wiring behind the contactor. Mounting position is flexible: +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward/backward. Clearance requirements: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the sides — tight enough for dense DIN-rail arrays. Wire terminals are screw-type, accepting solid or stranded conductors from 0.5 to 4 mm² (single) or two conductors per terminal (2x 0.5...1.5 mm², 2x 0.75...2.5 mm², 2x 4 mm²). No special ferrules required for stranded, but they help in multi-wire terminations.
Environmental and life ratings
Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. The storage limit covers transit and off-line periods — the contactor can sit in a cold warehouse without issue. Mechanical life is typical 30 000 000 operations — the contactor will outlast the machine's service life in most cycling applications. Switching frequency limits are per duty class, so match the load profile to the rating.
