Product details

The 3RT6018-1AM22: Size S00 contactor, rated 13 kW at 400 V and 60 °C ambient — that's the derated figure for a warm panel, not the optimistic 40 °C number. At 690 V it handles 22 kW, at 230 V it's 7.5 kW. Insulation voltage is 690 V rated, so it coordinates with 400 V and 690 V systems without derating the creepage distances.

DIN rail mount, side-by-side, screw terminals

Side-by-side mounting is permitted — no air gap required between contactors, so you can pack them tight in a panel. That covers most panel layouts without special brackets. At 60 °C the minimum conductor is 2.5 mm² for full rated current.

Switching frequency and coil data

AC-3 maximum is 750 ops/h, AC-4 is 250 ops/h.

Substance prohibitance date 05/01/2012 aligns with RoHS compliance — the contactor meets the EU RoHS directive for lead, mercury, cadmium, and other restricted substances.

Frequently asked questions

What is the 3RT6018-1AM22 motor rating at 400 V?

At 400 V and 60 °C ambient, it's rated 13 kW. At 690 V it handles 22 kW, at 230 V it's 7.5 kW — all at 60 °C. The 40 °C ratings would be slightly higher.

Does the 3RT6018-1AM22 mount side-by-side without gaps?

Yes, side-by-side mounting is permitted with no required air gap between contactors. That lets you pack them tight on DIN rail.

What compliance documentation does Siemens provide for 3RT6018-1AM22?

The contactor meets RoHS with a substance prohibitance date of 05/01/2012.
