The YHZC/C series low-voltage distribution system surge protector is designed to suppress surges in low-voltage electrical devices. It is a modular combination of surge protection devices that can protect downstream electrical devices and equipment (such as EDP systems, communication systems, etc.) from surge hazards caused by switch actions, static discharge, induced lightning strikes, or direct lightning strikes. It is used for the second level protection of low-voltage distribution systems.

Main features of the product:

◎ High throughput, low residual pressure, fast response speed, and no continuous flow

Equipped with a built-in thermal release device, the protector can automatically disconnect in case of overheating or breakdown failure

Modular design with standard 35MM rail installation, very easy to install and maintain

The window color displays the working status, with green indicating normal and red indicating product malfunction

◎ Optional remote signaling terminal for easy remote alarm control

effect

Lightning discharge may occur between or within cloud layers, or between cloud layers and the ground; In addition, the internal surges caused by the use of many large capacity electrical equipment have become a focus of attention, affecting the power supply system (Chinese low-voltage power supply system standard: AC 50Hz 220/380V) and electrical equipment, as well as lightning protection and surge protection.

The lightning discharge between clouds and the ground is composed of one or several individual lightning strikes, each carrying a high amplitude and short duration current. A typical lightning discharge will consist of two or three lightning strikes, with a time interval of approximately one twentieth of a second between each lightning strike. Most lightning currents fall within the range of 10000 to 100000 amperes, with a duration generally less than 100 microseconds.

Due to the use of high-capacity equipment and variable frequency devices, the power supply system is facing increasingly serious internal surge problems. We attribute it to the influence of transient overvoltage (TVS). Any electrical device has an allowable range of power supply voltage. Sometimes even narrow overvoltage surges can cause damage to the power supply or the entire device. The destructive effect of transient overvoltage (TVS) is like this. Especially for some sensitive microelectronic devices, sometimes even small surges can cause fatal damage.
