The Siemens SIRIUS 3RT1016-2AP01-1AA0 is a Size S00 power contactor rated for switching motor loads up to 4 kW at 400 V AC-3, with a 24 VDC coil. It's built for DIN-rail mounting on a 35 mm rail per DIN EN 50022, using either screws or the integrated snap-on feature — a standard fit for any industrial control panel.
The operational current at AC-12 (resistive load) is 10 A, which covers heater banks or lighting circuits where the inrush is minimal. For DC switching, the contactor is rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — the voltage-dependent derating curve is steep because DC arcs are harder to extinguish. This matters for selectivity studies and fuse sizing in the panel.
Mounting and Integration Details
Side-by-side mounting is allowed with a 6 mm gap at the side for heat dissipation. Front-side protection is IP20, meaning it's finger-safe for the panel builder but not washdown-rated. Both main and auxiliary/control circuits use spring-loaded terminals, accepting 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG). No screwdriver torque check needed — the spring cage holds firm against vibration, which is a plus on a press line or conveyor drive.
Mechanical endurance is listed at 30 million operations — a high cycle count that suits frequent-start applications like conveyor systems or packaging lines.
