SPD Single Phase Surge Arrester , 275V 3KA Electrical Surge Protectors Long Service Time

Product Details

Surge protector is a lightning protection measure adopted by Zhejiang toer Electric Co., Ltd. for electrical system. It is used to protect the lightning protection device of home housing. The lightning protection device is used to protect sensitive lines and protect the lightning and direct lightning or other instantaneous overvoltage.
The lightning arrester adopts the multi-stage protection circuit, selects the brand components and makes use of the advanced production technology. It has the characteristics of large flow capacity, low residual pressure level, sensitive reaction, stable performance, reliable work and so on.

Working principle of product

Surge protector is an indispensable device for lightning protection of electronic equipment. It used to be called "lightning arrester" or "over voltage protector".
The function of a 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.

Product features

1. low output residual pressure to further ensure safety

2. traffic flow to further improve safety

3. advanced production process and beautiful appearance

Product specification

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.

Notice of product

1. the protected equipment must have good grounding, and the grounding impedance value is according to the relevant standard.

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. surge protector is installed with 35MM standard guide rail
