The Siemens 3RT1316-1AU60 is a SIRIUS S00 power contactor with four normally-open main poles, rated for 4 kW at 400 V in AC-2 duty. The IP20 finger-safe enclosure suits panel-mount installations where the contactor is protected inside a cabinet.
Ratings and coordination
The auxiliary contact block switches 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — covering typical PLC-level control signals and small relay loads.
Side-by-side mounting is permitted with 6 mm spacing to adjacent devices. The screw terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, up to a maximum of 2x (0.75 to 4 mm²) — sufficient for the 4 kW motor circuit.
