Power Surge Protective Device 80kA

SPD 80KA, standard type MOV SPD 1, Test standard: IEC61643-1 2, Imax: 80kA, In: 40kA, Up: 2.1 kV 3,20 years` experience

NKP-DY-I-80/385

SPD surge arrester /surge protective device 80KA 

NKP Power series SPD from KEJIA is usually be used in the IT, TT, TN-C, TN-S and etc power supply system of AC 50Hz, rated voltage up to 385V, to protect from direct and indirect lightning impulse and other transient over voltage. As the conditions of IEC61643-1:1998-02 standard, Class B surge protective device, it is category B surge protective device. SPD has two protection modes: MC and MD. 

Functions

protection of heavy-loaded electrical circuits from overloadused to protect not only particular consumers/circuits, but also the whole panelremarkable with high reliability of current characteristicscontrol: automatic switching off at exit failure and recovery after eliminating the danger
