The 3RT1016-1BE41: The AC-3 motor-switching rating is the one that governs real motor loads: 4.5 kW at 500 V and 5.5 kW at 690 V tell you the maximum three-phase induction motor this contactor can handle in standard starting duty. The coil holds at 24 V nominal and drops out below 18 V, typical for DC-operated contactors. Screw-type terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid/stranded, or up to 2x (0.75 to 4 mm²) with ferrules. That covers most panel wiring up to 4 mm² without needing ring lugs.
This contactor is built for motor control in industrial panels — starting and stopping three-phase induction motors on conveyors, pumps, fans, and compressors. The S00 frame size keeps the footprint compact at 45 mm wide, so it fits tightly on a DIN rail inside a standard enclosure.
Type 1 coordination allows a 35 A fuse. This matters for selectivity studies in the panel design.
