Thor surge protector Industrial Low Voltage surge protection device
Brief introduction
When the equipment is short circuited and the power
switch is going to happen, it may cause surge, and surge occurs in
just a few millisecond, which will cause great harm to the
equipment. The surge protector can react and absorb the huge energy
suddenly, so as to protect the connecting devices from being
damaged.
Product features
1. limit the precision of the voltage to say how much!
2. installation and use of convenient novice can also be
easy to install
3. strict product structure, meticulous and comprehensive
protection
4. core components are strictly screened, stable performance
and reliable operation.
Use of attention
1. device and the SPD set up the equipotential connection.
2. Needs to carry out the energy coordination of multilevel SPD
3. In order to limit the inductive coupling between the protected
part after installation and the unprotected device part, 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
The power surge protector is divided into two parts: explosion
proof box type and modular type. A varistor with excellent
nonlinear characteristics is adopted. Under normal conditions, the
surge protector is in extremely high resistance state, and the
leakage current is almost zero, thus ensuring the normal power
supply of the power supply system. When the power system surge
overvoltage, the power surge protector immediately passes in the
nanosecond time, limits the amplitude of the overvoltage to the
safe working range of the equipment, and releases the surge energy
into the ground. Subsequently, surge protector rapidly changes to
high resistance state, so that normal power supply is not affected.
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.
Company profile
Incorporated in 2006, Zhejiang Thor Electric Co., Ltd has built everything to offer a wide range of innovative and reliable surge protection solutions and products.
