The 24 VDC coil is standard for PLC-driven panels. Three normally-open main contacts handle the power circuit; there are no auxiliary contacts built into this base unit. Short-circuit coordination is specified: Type 2 coordination requires a 20 A gL/gG fuse, while Type 1 coordination allows a 35 A gL/gG fuse. This matters for selectivity studies and panel SCCR calculations — the fuse size directly affects the let-through energy the contactor must survive. The screw-type terminals accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) solid, or up to 2x (0.75 to 4 mm²) solid — covering the common control and power wiring sizes for a 4 kW motor circuit. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. Front IP20 protection means the contactor is safe from finger contact when mounted in an enclosure — standard for control panels.","metaTitle":"Siemens SIRIUS 3RT1016-1AR11 Power Contactor, S00 Frame, 4 k","metaDescription":"Siemens SIRIUS 3RT1016-1AR11 power contactor, S00 frame, 3-pole, 4 kW AC-3 at 400 V, 24 VDC coil, screw terminals, current production.
