Product details

SIRIUS S00 power contactor — 10 A AC-3, 230 V coil

The Siemens 3RT6016-1AK21 is a SIRIUS S00 power contactor rated for AC-3 switching at 10 A at 230 V, with a maximum operating voltage of 690 V AC-3/AC-3e. The 230 V AC coil draws 10 A at rated value, and the contactor handles motor loads up to 7.5 kW at 230 V and 13 kW at 400 V at 60 °C ambient. Screw-type terminals on the main circuit accept 2x (0.5 to 2.5 mm²) solid or stranded wire, with a minimum permissible 4 mm² at 40 °C.

Pollution degree 3 suits industrial environments with conductive contamination.

Switching performance and compliance

Rated for 10,000 switching cycles per hour at AC load, with maximum rates of 1,000/h for AC-1, 750/h for AC-3/AC-3e, and 250/h for AC-4. Mechanical endurance is 30 million operations typical. The contactor meets RoHS compliance with substance prohibition date of May 1, 2012.

Frequently asked questions

What are the key ratings for 3RT6016-1AK21?

AC-3 rated current is 10 A at 230 V, with maximum AC-3/AC-3e voltage of 690 V. Motor power at 60 °C is 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V. The 230 V AC coil draws 10 A at rated value.

Where can I buy 3RT6016-1AK21?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 3RT6016-1AK21 drop into a panel specified around 3RT6015-1AF02?

Both are SIRIUS S00 contactors with the same 45 mm width and DIN-rail mounting, so the footprint is identical. The main difference is the coil voltage — 3RT6016-1AK21 uses a 230 V AC coil, while 3RT6015-1AF02 uses a different coil voltage. Verify the coil voltage matches your control circuit before swapping.

What compliance documentation does Siemens provide for 3RT6016-1AK21?

RoHS compliance is confirmed with a substance prohibition date of May 1, 2012. The contactor is designed to meet IEC/EN standards for industrial control equipment (pollution degree 3, rated insulation voltage 690 V).
