Household power supply lightning protector, 385v surge protector, 40KA, primary power supply protection

Product introduction

Surge protector is a lightning protection measure developed by Zhejiang tohr Electric Co., Ltd., which is independently developed for electrical system.
The circuit protection is made up of a powerful diode solid state discharge tube; basic and fine protection is based on automatic fault protection device technology. In thermal overload, the device moves the two ends of the original lightning protection together, thus causing the damage of the surge.

Product specification

Product features

1. leakage current is small, the response time is fast, and the residual pressure is low

2. copper fittings have good electrical conductivity

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

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

Notice of product

1. surge protector is installed with 35MM standard guide rail

2. the energy coordination of multilevel SPD

3. 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.

4. standard RJ45 interface can be conveniently connected to the front end of the protected equipment. The grounding path should be as short as possible, and the length should not exceed 1.5 meters.

Working principle of product

During the operation of the equipment, the lightning arrester will play a protective role once the abnormal voltage occurs. When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment.
When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally. The main function of the lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect the power equipment.

Structure and Principle

SPD is a port, shocking protection, indoor-mounted installation, voltage-limited.

SPD hold disconnector inside, when SPD breakdown failure by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is working properly, visible window display green, it display red when it breakdown and disconnect.

1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground protection module, apply to TN-S, TN-C-S and other power supply system.
