Surge Protector Lightning Arrester Lightning Protector
Application range
NKP-DY-II-40 series are applied to equipotential bonding of the main low voltage distribution boxes in the building, providing overvoltage protection arising from the class C lightning strike to power supply system or disoperation. (Option from standard IEC61643- 1 and GB50343)
Main Feature:
1. Plug and play design, live-wire replacement, easy maintenance;
2. Build-in temperature control circuit breaker, high security performance;
3. Green light in notice window indicates normal; red indicates broken, replacement notice, which is clear and easy distinguished;
4. Optional telesignalling monitoring interface, realizable remote monitoring;
5. External bus-bar wire, single module free assembled, easy project construction;
6. Assembled 1P, 2P, 3P, 4P etc modes, applied to various electric network systems.
