Product details

Coil and auxiliary contact ratings

The 3RT2018-1AK62: At 230 V the contactor is rated 2 hp, which is the motor load ceiling for this coil voltage variant.

Switching frequency by duty class

The arcing time spans 4–15 ms at AC, with a typical 10–15 ms window — relevant for coordination with upstream protection.

Environmental and endurance specs

Mechanical endurance is 30 million operations typical, which suits high-cycle applications like conveyor or pump control.
