Integrator note — SIRIUS 3RT2016-1CP07-ZX95
The Siemens 3RT2016-1CP07-ZX95 is a SIRIUS power contactor in size S00, rated for switching motor loads in control panels. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the coil terminals are screw-type — no special tooling needed for the panel builder. The 45 mm width and 117 mm depth fit standard enclosure layouts; plan for 10 mm clearance upwards, forwards, and downwards, and 6 mm at the side for arc dissipation and airflow.
Duty-cycle and switching capacity
The contactor is rated for AC-3 duty at 750 operating cycles per hour maximum — that's the standard motor-switching class for squirrel-cage motors. For heavier AC-4 duty (plugging, inching), the maximum drops to 250 cycles per hour. The AC-1 resistive load rating allows 1,000 cycles per hour. Mechanical life is 10 million operations typical. The main contact rating is 20–12 (likely 20 A at 400 V AC-3, though the exact AC-3 current is not listed here). The arcing time is 10–15 ms, with a 7–13 ms make time at AC.
Wiring and environmental limits
Solid or stranded wire from 0.5 to 4 mm² is accepted. Operating temperature is -25 to +60 °C; storage range is -55 to +80 °C.
