2p surge protection switch SPD TRS4-C40 lightning protection lightning arrester switch 220V

Working principle of product

Under normal working condition, the lightning protection module is in a high resistance state. When the power supply line has lightning invasion or operation transient overvoltage, the lightning protection module will immediately pass through the response speed of nanosecond level, and limit the lightning overvoltage or transient overvoltage to the voltage range allowed by the electrical equipment, thus protecting the normal operation of the electronic equipment. After that, the lightning protection module quickly returns to the high impedance state without affecting the normal power supply of the grid.

Product specification

Brief introduction

Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system. It protects the sensitive lines from the damage caused by lightning induction voltage, power interference, electrostatic discharge and so on.
The housing is installed on the 35mm electric rail, and it can be applied to single-phase and three-phase power supply lines and modular design through different combinations.

Product features

1. copper fittings have good electrical conductivity

2. can withstand high lightning shock

3. high-performance chips can react quickly when problems arise.

4. cut off the line when undervoltage occurs, and reset automatically after restoration.

Notice of product

1. 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.

2. connect the grounding wire of the lightning protector with the ground wire of the lightning protection system.

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

4. ambient air temperature is no more than +40 C and no less than -5 C, and the average value of 24 hours is no more than +35 C.
