Two In One Single Phase Surge Protector , 420V 40KA Mains Surge Protection Devices

Network two in one protector device, power network, signal unity protection.

Product introduction

Surge protector is an electronic device that provides security protection for all kinds of electronic devices, instruments and communication lines. When the peak current or voltage is suddenly produced in the electrical circuit or communication line because of the external interference, the surge protector can guide the shunt in a very short time, thus avoiding the damage to the other equipment in the circuit. It is usually installed in the floor distribution box, computer center, telecommunication machine room, elevator control room and so on.

Product features

1. strict product structure, meticulous and comprehensive protection

2. strict product structure, meticulous and comprehensive protection

3. new technology, high energy, gap discharge electrode N-PE.

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.

Product specification

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.

Notice of product

1. the protected equipment must have good grounding, and the grounding impedance value is according to the relevant standard.

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

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