220V surge arrester power surge protector device SPD 20

Surge protectors produced according to international standards

Product description

Surge protector is an electronic device that provides safety protection for various electronic devices, instruments and communication lines. It is mainly used to limit overvoltage and discharge electric current. Surge protector is usually connected with protected equipment. When overvoltage is generated, it can play the role of shunting and voltage limiting. Prevent excessive current and voltage from damaging the equipment.

Product features

1. module is designed and installed conveniently and can be replaced directly.

2. leakage current is small, the response time is fast, and the residual pressure is low

3. indicator device, normal (green) and red (fault).

4. operation, high energy, gap discharge electrode N-PE.

Product specification

1. Rated Operating Voitage(UC):275V

2. Voltage protective level(UP):1.1KV

3. Max discharge current(IMAX):20KA

4. Nominal discharge current(IN):10KA

Working principle of product

1. quasi interface and connection mode;

2. the input / output interface of the quasi lightning arrester is input to the external line and the output device.

3. earth lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.
The grounding of the

4. lightning arrester shall be connected to the grounding grid through an electronic switch.

Use of attention

Surge protector is an indispensable device in lightning protection of electronic equipment. It used to be called "lightning arrester" or "overvoltage protector". The function of surge protector is to limit the transient overvoltage to the power line and signal transmission line within the electric pressure range that the equipment or system can bear, or to inflow the powerful lightning discharge into the ground. The protected equipment or system is not damaged by impact.
