The Siemens 3RT6018-1AR62 is a SIRIUS S00-frame power contactor rated for motor switching at 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V — all at 60 °C ambient, which is the real-world panel temperature, not the ideal 40 °C lab figure. That means it handles a 22 kW motor on a 690 V line without derating in a warm enclosure. The AC-3 switching frequency maxes at 750 operations per hour, so it's sized for cyclic loads like conveyors or compressors, not continuous duty. Screw-type terminals on the main circuit accept up to 2x 4 mm² stranded — typical for a 7.5 kW motor feed at 230 V.

Frequently asked questions
What are the motor ratings for 3RT6018-1AR62?
At 60 °C ambient, it is rated for 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V. These are the AC-3 motor switching ratings that govern real panel conditions.
Will 3RT6018-1AR62 fit a panel designed for 3RT6018-1AB02?
Yes — both are S00-frame contactors with identical 45 x 57.5 x 73 mm dimensions and the same DIN rail mounting pattern. The difference is the coil voltage: 1AR62 is a 24 VDC coil, while 1AB02 is a 24 VAC coil. Wiring and footprint are interchangeable.
Where can I buy 3RT6018-1AR62?
This part is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ — no stock figures or lead-time numbers are published here.
