Product details

Rated at 10 A at 24 V, this contactor handles auxiliary switching at lower voltages as well — 2 A at 48 V and 60 V, 1 A at 110 V, and 0.9 A at 125 V. The 24 VDC coil is the standard control voltage for many industrial PLC outputs, so it's a common drop-in for panels running 24 V control logic. Mechanical service life is rated at 30,000,000 operations, and the contactor is approved for switching frequencies up to 1,000 cycles per hour under AC-1 resistive loads, 750 under AC-3 motor duty, and 250 under AC-4 (inching/jogging). That means it's built for continuous cycling, not just occasional on/off.

That flexibility helps when fitting into tight or odd-angle panel layouts. Wire terminations accept solid or stranded conductors from 0.5 to 4 mm², and the screw terminals can take two conductors per clamp — 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm². That's handy for daisy-chaining control wiring without extra terminal blocks.

Auxiliary and switching specifics

The main contacts are rated for 20 to 12 A depending on the utilization category — the AC-1 resistive rating is the highest, while AC-3 motor switching is the typical application for this frame size. At 230 V, the contactor is rated for 0.75 hp, and at 400 V it handles 3 A. That makes it suitable for small motors, pumps, fans, and conveyor drives up to about 0.55 kW at 400 V three-phase.

Frequently asked questions

Will the 3RT2015-1AK61 drop into a panel specified for the 3RT2015-1AT62?

Both are size S00 SIRIUS contactors with the same physical footprint (45 mm width, 58 mm height, 73 mm depth) and same DIN rail mounting. The main difference is the coil voltage — the 1AK61 uses a 24 VDC coil, while the 1AT62 uses a different coil voltage. If the panel wiring and control voltage match 24 VDC, it is a direct mechanical and electrical fit.

What are the key ratings for the 3RT2015-1AK61?

24 VDC coil, 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V. Mechanical life 30 million operations. Switching frequency up to 1,000 cycles/h AC-1, 750 AC-3, 250 AC-4.

What conductor sizes does the 3RT2015-1AK61 accept?

Solid or stranded 0.5 to 4 mm². Screw terminals accept two conductors per clamp: 2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or 2x 4 mm².

What compliance documentation is available for this contactor?

The evidence does not list specific compliance marks (UL, CSA, CE, RoHS, REACH) for this order code. As a standard Siemens SIRIUS product, it typically carries CE and UL/CSA markings, but confirm the specific certification for your jurisdiction when ordering.
