Product details

SIRIUS S00 power contactor — 3RT6018-1BM42

The Siemens 3RT6018-1BM42 is a SIRIUS-branded power contactor in the S00 frame size, designed for switching three-phase motor loads up to 13 kW at 400 V under AC-3 duty (690 V rated insulation voltage).

AC-3 motor switching and power ratings

Rated for AC-3 switching at 690 V maximum, the contactor delivers 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V — all at 60 °C ambient. The AC-3e maximum operating rate is 750 cycles per hour, with AC-4 (plugging/inching) limited to 250 cycles per hour. For resistive loads (AC-1) the rate climbs to 1 000 cycles per hour.

Panel fit and mounting flexibility

The 45 mm wide, 57.5 mm high, 73 mm deep footprint fits standard S00 contactor spacing. Screw terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm² solid/stranded, plus AWG equivalents 2x (20…16), 2x (18…14), or 2x 12.

Frequently asked questions

What are the key power ratings for 3RT6018-1BM42?

Under AC-3 duty at 60 °C, it delivers 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V. The maximum AC-3e switching rate is 750 cycles per hour.

Will 3RT6018-1BM42 drop into a panel specified around 3RT6018-1AB02?

Both are S00 frame contactors with the same 45 mm width, 57.5 mm height, and 73 mm depth, using screw-type terminals and 35 mm DIN rail mounting — so the panel cutout and wiring layout are identical. The difference is in the coil voltage; verify the control circuit matches the 1BM42's rated coil voltage before swapping.

What compliance documentation does Siemens provide for 3RT6018-1BM42?

The product carries a substance prohibitance date of 05/01/2012, indicating RoHS/REACH compliance for that cutoff. The insulation rating is 690 V rated value with pollution degree 3, and the operating temperature range is -25 to +60 °C with storage from -55 to +80 °C.

How do I get current pricing and availability for 3RT6018-1BM42?
