Wind power industry

In wind power generation, both DC contactors and AC contactors are used, depending on the specific application circuit. The current rating varies widely from a few amperes to several thousand amperes, determined by the circuit function (main circuit/auxiliary circuit) and the power capacity of the wind turbine system.
