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.
