   NKP-DY-I-100/385/4P

SPD surge arrester /surge protector/surge protective device 100KA 

NKP Power SPD from KEJIA is usually be used in the IT, TT, TN-C, TN-S, TN-C-S and etc power supply system of AC 50/60Hz, rated voltage up to 380V, to protect from direct and indirect lightning impulse and other transient over voltage. As the conditions of IEC61643-1:1998-02 standard, Class I surge protective device, it is category B surge protective device. SPD has two protection modes: MC and MD, SPD is in compliance with GB18802.1/IEC61643-1 standards. 

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
