Sensitive Electric Single Phase Surge Arrester , UC 320V 15KA Low Voltage Surge Protector

Type 1 Surge Protection Devices protect sensitive electronics from damaging effects of electrical surges.

Brief introduction

Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system, which is used to protect sensitive lines from lightning induction voltage, voltage fluctuation interference, electrostatic discharge and shock surge caused by large load start-up. It is widely used in family housing, third industry and industrial field.

Product Installation

With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35mm²

At front of spd each pole must be setted protection---used fuse or miniature circuit breaker lightning current SPD protection,after SPD breakdown to short circuit protection.

SPD install on protected line(equipment) to the front and connected to the supply line. A class products install in the building home-entry line hold larger surge current total distribution box. B, C class products most install on the floor distribution box, D class products close to the front-end equipment that smaller surge current, smaller residual voltage place.

Working principle of product

The working principle of surge protector is a high resistance open state with a low voltage, low resistance and short circuit state at high pressure, and a combination of over voltage protection electronic devices which can withstand hundreds of amperes and large current in parallel on the power supply line and signal transmission line. When encountering lightning and high voltage and high current, it will appear short circuit immediately, and at the same time, the total power switch will be disconnected, so that the device will be protected.

Use of attention

1. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.

2. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.

3. In order to limit the inductive coupling between the protected part after installation and the unprotected device part, we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.

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.
