220V single-phase surge protector Width 18mm and 14mm optional

Product introduction


The surge protector is a lightning protection measure adopted by Zhejiang toer Electric Co., Ltd. for the electrical system. The product is a surge protector for the plug type low-voltage distribution system, including the replaceable components. The voltage limiting element is composed of a metal oxide varistor. Each varistor requires an independent disconnector. The principle of the disconnector is a heat release. The function is disconnected through the low temperature welding point and is separated from the metal rod by its own elastic action. After disengagement, the red indication will appear in the transparent window on the front side of the surge protector.

Product Installation

With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35mm²

At front of spd each pole must be setted protection---used fuse or miniature circuit breaker lightning current SPD protection,after SPD breakdown to short circuit protection.

SPD install on protected line(equipment) to the front and connected to the supply line. A class products install in the building home-entry line hold larger surge current total distribution box. B, C class products most install on the floor distribution box, D class products close to the front-end equipment that smaller surge current, smaller residual voltage place.


Product specification

1. Rated Operating Voitage(UC):385V

2. Voltage protective level(UP):1.5kv

3. Max discharge current(IMAX):20KA

4. Nominal discharge current(in):10kA

5. Ressponse time(NS):<25


Working principle of product


When the surge protector has no voltage, the impedance is very high, which means that the circuit breaker is open. When the voltage occurs, the impedance drops to a few Europe, and the surge current will flow through the surge protector and will not enter the device. At the same time, because the surge protector has a small impedance at this time, the voltage on both sides of the surge is relatively small, and because he is in parallel with the protected equipment, it prevents the equipment from suffering from large surge power. Pressure, so as to play the effect of discharge and pressure limiting.

Use of attention


1. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.


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


3. 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.

Product features


1. traffic flow to further improve safety


2. core components are strictly screened, stable performance and reliable operation.


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