The KA switch combines the benefits and functions of the established KG and KH switch families in a new product line. The compact master maintenance switch has been developed for machine tools, power distribution and control cabinets, and all areas of applications requiring high reliability. The large connection space allows the use of finger-safe IP 20 terminals to connect different cable cross sections. The KA series currently offers threaded connections, and a ring cable connection product for this series will be available soon.
