DC surge protector for industrial production, 385v power protector,
high voltage cabinet.
Product introduction
The surge protector is a lightning protection measure adopted by
Zhejiang toer Electric Co., Ltd. for the electrical system. It is a
lightning protection measure used in the circuit system. It is an
important manifestation of internal lightning protection.
The device is protected from overvoltage damage caused by system
induced lightning and electrostatic discharge, and effectively
protects against surge and overvoltage protection.
Working principle of product
During the operation of the equipment, the lightning arrester will
play a protective role once the abnormal voltage occurs. When the
protected device is running under normal working voltage, the
arrester will not work, and it will be regarded as a circuit for
the ground. Once the high voltage is present and the insulation of
the protected equipment is endangered, the lightning arrester acts
immediately and leads the high voltage impact current to the earth,
thus limiting the amplitude of the voltage and protecting the
insulation of the electrical equipment.
When the overvoltage is gone, the arrester is restored to its
original state quickly, so that the system can supply electricity
normally. The main function of the lightning arrester is to reduce
the voltage value of the protected equipment through the action of
parallel discharge gap or nonlinear resistance, and to reduce the
voltage value of the protected equipment, so as to protect the
power equipment.

Product features
1. high-performance chips can react quickly when problems arise.
2. cut off the line when undervoltage occurs, and reset
automatically after restoration.
3. fastening slideway buckle design is very difficult to fall off
4. leakage current is small, the response time is fast, and the
residual pressure is low
Notice of product
1. 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.
2. in order to avoid unnecessary induction loops, we should mark
the PE conductor of each device.
3. determine the discharge current path
4. when installing, pay attention to the cable entering and leaving
the surge protector. The cables should be separated to avoid the
two coupling of surge.
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.
