Single phase domestic surge arrester surge protective device

Brief introduction

Surge surge arrester is a lightning protection measure adopted by Zhejiang tol Electric Co., Ltd. to independently develop and produce circuit protector. It is widely used in family housing, the third industry and the industrial field to avoid overvoltage damage such as induction lightning and electrostatic discharge introduced by the system. It has the characteristics of low residual pressure, sensitive reaction, stable performance, reliable work and so on.

Product specification

1. Rated Operating Voltage(UN):380V

2. Max continuous operating voltage(UC):275V

3. Voltage protective level(UP):1.3KV

4. Max discharge current(IMAX):40KA

5. Nominal discharge current(IN):20KA

Working principle of product

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

Use of attention

1. determine the discharge current path

2. in order to avoid unnecessary induction loops, we should mark the PE conductor of each device.

3. the energy coordination of multilevel SPD

Product features

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

2. with the power status indication, it indicates the working state of surge protector.

3. built-in overheating and temperature control circuit breaker
