Low residual high performance type 2 surge protection device

Product Details


Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system. It is suitable for the power supply system with 50/60HZ and rated voltage 220V/380V.
The protection of indirect lightning and direct lightning impact or other instantaneous overvoltage surge is suitable for household housing, the third industry and the requirements of industrial surge protection.

Product features


1. new technology, high energy, gap discharge electrode N-PE.


2. detachable assembly and pluggable convenience


3. safety insulation of fire retardant and high flame retardant material


4. self protection voltage is more than self protection, automatic disconnection and recovery.


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


2. determine the discharge current path


3. surge protector is installed with 35MM standard guide rail


4. in order to limit the inductive coupling between the protected part after installation and the part of the unprotected equipment, we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.


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.



Company profile
