40KA 385v DCElectrical Surge Protection Devices Alarm Indicating Long Service Time

3P lightning protector TRS4-C40 40KA voltage 385v DC surge

Brief introduction

The surge protector is a lightning protection measure adopted by Zhejiang toer Electric Co., Ltd. for the electrical system. It is a protective device for lightning protection and pressure protection in household, third industry and industrial fields.
It is mainly used to limit overvoltage and discharge electric current. Surge protector is usually connected with protected equipment. When overvoltage is generated, it can play the role of shunting and voltage limiting. To prevent excessive current and voltage damage to equipment, play the role of protection devices.

Working principle of product

In the equipment system, the inductive or capacitive coupling voltage is caused by the lightning shock and the switching operation of the upstream power supply system. Therefore, the surge may damage the photovoltaic modules and inverters and other devices. This will cause serious consequences for the operation of the system. The surge protector is a DC power defense specially designed for this purpose. The lightning module, once the high voltage, and endanger the insulation of the protected equipment, the lightning arrester acts immediately, the high voltage impact current guide the earth, thus limiting the voltage amplitude, protecting the insulation of the equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so as to protect the power equipment.

Product specification

Product features

1. tunnel type terminal connection, tighter wiring is more compact.

2. cut off the line when undervoltage occurs, and reset automatically after restoration.

3. fastening slideway buckle design is very difficult to fall off

4. detachable assembly and pluggable convenience

Notice of product

1. it should match the working voltage of the protected equipment. Please install according to the installation sketch.

2. lightning protector's input port (IN) is connected to the signal channel, and the output terminal (OUT) is connected with the input end of the protected device, so it can't connect with the signal.

3. when installing, pay attention to the cable entering and leaving the surge protector. The cables should be separated to avoid the two coupling of surge.

4. generally speaking, it is better to separate the protected conductor from the non protected conductor, and it should be separated from the ground wire. At the same time, in order to avoid transient orthogonal coupling between power cables and communication cables, necessary measurements should be made.
