In modern power systems, the threat of lightning cannot be ignored. They can not only cause direct damage to buildings, but also invade indoors through power supply lines, causing serious damage to low-voltage power supply and distribution systems and electrical equipment. In order to meet this challenge, the Lightning arrester SPD385-40A-MH came into being. With its excellent performance and design, it has become an important device for protecting the safety of power systems.

1. “3+1″ protection circuit: multi-level protection

Lightning arrester SPD385-40A-MH adopts a unique “3+1″ protection circuit design, which provides multi-level protection and ensures that the power system can be effectively protected under different lightning strike intensities. “3+1″ refers to three-phase power supply plus neutral line. This configuration enables the surge arrester to fully cover all parts of the power system and provide all-round protection.

2. Built-in protection function: intelligent monitoring

In addition to basic lightning protection functions, Lightning arrester SPD385-40A-MH also has built-in overheating and overcurrent protection functions. This function can automatically disconnect the power supply when an abnormality occurs in the power system, such as overheating or overcurrent, to prevent equipment damage and fire. This intelligent monitoring mechanism greatly improves the safety and reliability of the system.

3. Class C lightning protection: high standard protection

Lightning arrester SPD385-40A-MH can provide Class C (Class II classification test) lightning protection, which is one of the highest lightning protection levels specified by the International Electro technical Commission (IEC). This means that the lightning arrester can withstand high-intensity lightning strikes and protect low-voltage power supply and distribution systems from lightning.

4. Integrated design: easy installation and maintenance

The integrated base design of Lightning arrester SPD385-40A-MH is not only beautiful, but also greatly facilitates installation and maintenance. This design reduces the complexity of the installation process and is also convenient for daily inspection and maintenance.

5. Remote signal alarm interface: remote monitoring

The lightning arrester is also equipped with a remote signal alarm interface (dry contact), which allows users to remotely monitor the working status of the lightning arrester. Once the system is abnormal, users can be notified immediately and take timely measures to avoid potential risks.

The Lightning arrester SPD385-40A-MH has become an indispensable safety guardian for low-voltage power supply and distribution systems with its comprehensive performance and user-friendly design. It not only improves the lightning protection capability of the power system, but also provides users with a more convenient and reliable power use experience.
