Kumwell KSMH.SG series of surge peotective devices has been developed to protect againts the effects of induced voltages onto data, signal and communication.
It is intended forthose applicatios where high ground potential rises may frequency occur, such as in location close to electric railways.
The circuit topology consists of amulti- stage protector providing both commom (longitudinal) mode and differential (transverse) mode protection.
Coarse protection is provided by a three teminal GDT while fine protection is provided using a high speed silicon avanlanche diodes or metal oxide varistor stage.
