AC surge protection device 40KA power lightning protection surge arrester

Three-phase power surge protection device has remote signal function

Brief introduction

Surge protector, also called lightning arrester, 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 very short time, thus avoiding the damage of the surge to other equipment in the circuit.

Use of attention

1. surge protector is installed with 35MM standard guide rail
2. determine the discharge current path
3. the wire that marks the extra voltage drop caused by the device terminal.
4. in order to avoid unnecessary induction loops, we should mark the PE conductor of each device.

Product features

1. multi-functional overvoltage protection, lightning and overpressure are no longer afraid of disasters.

2. the speed of response is 0.001 seconds, and the voltage is controlled in the range that the equipment can withstand.

3. low output residual pressure to further ensure safety

4. traffic flow to further improve safety

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

The function of the surge protector is to limit the transient overvoltage to the power line and the signal transmission line within the voltage range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground, and to protect the protected equipment or system from being damaged by the impact.
