Standard contactors and protection devices in the xStart range are made ready for SmartWire-DT connectivity simply by adding an interface module, in exactly the same way that an auxiliary contact block is fitted.
The new interface modules for PKE motor protection circuit breakers give users of SmartWire-DT access to versatile electronic motor protection. Each of the units in the PKE family covers a wide range of motor currents, thereby minimising the number of variants that have to be stocked. The units also offer tripping classes that can be set from CLASS 5 to CLASS 20, which means that optimum protection can be provided for all types of drive, irrespective of the start-up conditions.
Other benefits of PKE motor protection circuit breakers include reduced heat dissipation and energy losses compared with devices that use conventional bimetal protection elements, high accuracy and stability, and the ability to transfer data, including real-time current flow information, to a PLC or similar external device.
