Product Description
Provides protection against Short-circuit/Overload current and function of isolation.
High breaking current withstand capacity
Applicable to terminal and pin/fork type busbar connection
Equipped with finger protected connection terminals
Fire resistant plastic parts endures abnormal heating and strong impact
Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
Independent of power supply and line voltage, and free from external interference, voltage fluctuation
Application

NDU1-Dseries is suitable for TT power supply system with AC 50/60Hz,230/400V and below. Its design based on IEC6143-1, GB18802.1 and GB50057 standard requirements, can discharge 100KA lightning over current, normally installed at incoming line of the main distribution box of buildings.
B type lightning current SPD used for equipotential connection during lightning, installed at the LPZOA zone or junction area of LPZ1 zone, normally installed at the incoming line of low voltage main distribution board.
Selection Principle

-Modularization - can replace the protection module without electricity cutoff.
-Big current - maximum can withstand 100KA(8/20µs)
-High speed - response time less than 25ns
- Status indication - the window color shows the working status : Green ( normal ), Red (fa
