SIRIUS S00 power contactor — 3RT1016-1AK61-ZX95
The Siemens 3RT1016-1AK61-ZX95 is a SIRIUS S00 frame power contactor rated for 10 A at 24 VDC and 5.5 kW at 690 V AC-3. It handles motor switching up to 4 kW at 400 V AC-2 and 8.5 A at 400 V AC-4 for reversing or plugging duty. The 45 mm wide body mounts on a 35 mm DIN rail per DIN EN 50022, saving panel space for high-density layouts.
Switching capability and coordination
DC switching covers 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — enough for small DC motor brakes or solenoid loads. AC-3 motor ratings reach 4.5 kW at 500 V and 5.5 kW at 690 V. For Type 2 coordination the contactor requires a 20 A gL/gG fuse; Type 1 allows a 35 A gL/gG fuse. Ambient operating range is -25 to +60 °C, with a maximum operating altitude of 2 000 m.
Termination and wiring
Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded conductors. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. Finger-safe IP20 protection on the front and terminals. Side-by-side mounting is allowed with a 6 mm clearance to adjacent devices.
