For AC-4 duty (plugging, inching), it carries 6.5 A at 400 V. Power ratings extend to 3.5 kW at 500 V and 4 kW at 690 V, covering common European and North American line voltages. The AC-1 resistive rating at 24 V is 10 A, and at 230 V it is 6 A — these govern heater and lighting loads, not motor starts. The AC-3 motor-switching rating is not explicitly listed, but the AC-2 and AC-4 figures bracket it: expect the contactor to suit a 3 kW motor at 400 V in standard starting duty. Pollution degree 3 confirms it tolerates conductive dust and humidity typical of industrial floors. ## Termination and Wiring Both main and auxiliary circuits use screw-type terminals. Wire range for solid conductors is 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²), with a maximum of 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16) and 2x (18 to 14), plus a single 12 AWG. This covers most panel wiring from signal-level to light power feeds. For Type 1 coordination (contactor may need replacement after a fault), the fuse rating is 35 A. This matters when laying out the protection scheme upstream. RoHS compliance is confirmed with a substance prohibition date of 01.07.2006, covering the EU RoHS directive.","metaTitle":"Siemens 3RT1015-1AK61 SIRIUS Power Contactor, S00, 3.5 kW at","metaDescription":"Siemens 3RT1015-1AK61 SIRIUS power contactor, size S00, rated 3.5 kW at 500 V and 4 kW at 690 V.
