Electromagnetic contactors of KNE U Series
General Information
KNE U contactors are self-resetting monostable electromagnetic devices with DC control circuits.
The contactors are designed for switching operations in electrical circuits with the DC voltage of up to 132 V and the AC voltage of up to 418 V, with frequency ranging from 50 to 1000 Hz; they may be used in critical equipment of both mobile and fixed facilities.
