The AC Module Lightning Protector (Model m40b3+n) from Shenzhen Techwin Lightning Technologies Co., Ltd. is designed to safeguard electrical systems from transient overvoltages caused by lightning or switching events. It operates at a nominal working voltage of 380V AC with a maximum continuous operating voltage of 385V AC, making it suitable for industrial and commercial power networks. The protector’s nominal discharge current is rated at 20 kA, with a maximum discharge current of 40 kA, providing robust protection under severe conditions.
Constructed with a protection level of ≤1500V at 20 kA (8/20µs waveform), the module responds in ≤25 nanoseconds, a critical feature for limiting voltage spikes in sensitive equipment. Its protection model covers L1/L2/L3-N and N-PE configurations, ensuring comprehensive coverage for three-phase systems. The unit’s IP20 protection grade and compact dimensions of 90×72×65 mm make it ideal for installation in control panels or distribution boards.
This lightning protector is widely used in data centers, telecom infrastructure, and industrial facilities where power quality and equipment safety are paramount. Buyers should confirm compatibility with their system’s voltage, current, and environmental conditions, as well as the module’s certification status for standards such as IEC 61643-11. The typical working temperature range of -40°C to +85°C and humidity tolerance up to 90% align with standard industrial requirements.
