SIRIUS S00 power contactor – panel fit and coil drive
The Siemens 3RT2016-1AK64-3MA0 is a SIRIUS power contactor in size S00, rated for switching motor and resistive loads in control panels. Its 45 mm width and 117 mm depth fit standard DIN-rail enclosures, and the screw-type coil terminals accept 0.5 to 4 mm² solid or stranded wire. The 24 VDC coil draws 6 A at rated voltage; breaking capacity on the auxiliary contacts is derated from 6 A at 24 V to 0.2 A at 440 V — check the voltage-specific values before committing the control circuit.
Mounting and environment
Snap-on mounting onto 35 mm DIN rail per EN 60715, or screw-mount. The contactor can be rotated ±180° on a vertical surface and tilted ±22.5° forward/backward — useful when panel layout forces an unconventional orientation. Operating temperature range is -25 to +60 °C; storage from -55 to +80 °C. Clearance: 10 mm above and below, 6 mm at the sides, 10 mm forward.
Switching frequency and duty class
Maximum switching rate depends on duty: 1000 cycles/h for AC-1 (resistive), 750 cycles/h for AC-2, AC-3, and AC-3e (motor start/run), and 250 cycles/h for AC-4 (plugging/inching). The arcing time is 10 to 15 ms at 50/60 Hz.
