220V electrical surge protective surge arrester 20KA surge protection device spd

Surge protection device for power supply system , lightning protection system

Working principle of product

When the surge protector has no voltage, the impedance is very high, which means that the circuit breaker is open. When the voltage occurs, the impedance drops to a few Europe, and the surge current will flow through the surge protector and will not enter the device. At the same time, because the surge protector has a small impedance at this time, the voltage on both sides of the surge is relatively small, and because he is in parallel with the protected equipment, it prevents the equipment from suffering from large surge power. Pressure, so as to play the effect of discharge and pressure limiting.

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 features

1. advanced production process and beautiful appearance

2. the product has many interfaces and is easy to use. It doesn't need to worry about the number of interfaces.

3. self protection voltage is more than self protection, automatic disconnection and recovery.

4. adopt the latest arc extinguishing technology to avoid fire.

Product specification

product description

The power supply surge protector, also known as the power supply lightning protection device, is suitable for the AC 50/60HZ, the rated voltage 220V/380V power supply system, the indirect lightning and direct lightning impact or other instantaneous overvoltage surge protection, suitable for home housing, the third industry and industrial field surge protection requirements, with relative phase, relative. The relative middle line, the middle line to the ground and its combination protection mode.

Use of attention

1. when the current carrying conductor is part of the closed loop, the circuit and the induced voltage decrease as the conductor approaches the circuit.

2. 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.

3. data line: more than 2.5mm2; when the length of more than 0.5 meters of more than 4mm2.
