Product details

Rated for AC-2 duty at 3 kW at 400 V, this contactor handles wound-rotor motor starting and reversing. 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.

Frequently asked questions

What is the closest functional second-source to the 3RT1015-1AK61?

The 3RT1017-1AP01 is a peer in the same SIRIUS S00 family but with a different coil voltage or auxiliary configuration. The 3RT1015-1AK61 uses a 24 V DC coil (based on the 10 A at 24 V rating) and screw terminals; verify the coil voltage and aux contact count before substituting.

What are the key ratings of the 3RT1015-1AK61?

AC-2 motor duty at 400 V is 3 kW. AC-4 at 400 V is 6.5 A. Power ratings are 3.5 kW at 500 V and 4 kW at 690 V. Mechanical life is 30,000,000 operations. Operating temperature range is -25 to +60 °C.

What wire sizes does the 3RT1015-1AK61 accept?

Solid conductors: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). AWG equivalents: 2x (20 to 16) and 2x (18 to 14), plus 1x 12 AWG.

What compliance documentation does the 3RT1015-1AK61 carry?

RoHS compliance with a substance prohibition date of 01.07.2006. The reference code per IEC 81346-2 is Q. IP20 protection on front and terminals. Pollution degree 3.
