Product Description

Class 2 12v Dc Surge Protector , 40KA Low Voltage Protection

Lightning Protection Device Solar PV 40kA Low Voltage DC Surge Protector Device

DC surge protection device (NDU6) used in lightning protection of solar photovotaic power generation system or other DC power supply system and make the system against lightning overvoltage.Built-in temperature control circuit technology,high security;indicator window green means normal,red to represent the fault,must be replaced and legible;optional remote communication interface,the realization of remote monitoring;high flow,high safety and stability. The product can be pluggable modular design,standard guide installation,selection of high-quality photovoltaic professional lightning protection devices,stable performance,built-in hot melt,flow in dual protection circuit,visualization window,normal green,red fault,large flow capacity,low residual voltage,fast response(nanosecond),with remote monitoring function,convenient remote monitoring(optional).


Performance characteristics:

Adopt the latest thermal separation technology, built-in thermal protection, automatic separation device for short-circuit failure, completely avoid fire;
The core components adopt internationally well-known brands, with excellent performance, stable and reliable work;

Lightning current arrestors OBV10-I-50 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions.The voltage-limiting,high-performance spark gaps provide several benefits.A short response time, a low protection level and high current leakage capability with long service life.


The main parameters:

Nominal working voltage Un: 12VDC
Maximum working current: 2A
Nominal discharge current In(8/20μs): 5kA
Maximum discharge current Imax (8/20μs): 10kA
Combination method: 1P
Response time: 25ns
Working environment: -40℃~+85℃
Installation method: rail installation


For protecting low voltage equipment from surge damages. Applied in pluggable SPD Class II (Class C) for TN power supply system. Designed according to IEC 61643-1 / GB 18802.1.

Main character:

1. Small volume, high discharge capacity, pluggable

2. Quick response

3. Double thermal disconnector devices, providing reliable protection.

4. Multifunctional terminal for connecting conductors and busbars

5. Green window will change when fault occurs and also provide remote alarm control contact at the same time.
