Power supply lightning protection , 4P surge surge protector
product description
Surge protector is a lightning protection device for home
housing. The lightning protector is used to protect sensitive lines
and protect the lightning and direct lightning surge or other
transient surge. 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.
Product features
1. traffic flow to further improve safety
2. use temperature control protection circuit, built-in
thermal protection
3. advanced production process and beautiful appearance
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.

Working principle of product
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.
Use of attention
1. the separation between the protected conductor and the UN
protected conductor is good, 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.
2. standard RJ45 interface can be conveniently
connected to the front end of the protected equipment. The
grounding path should be as short as possible, and the length
should not exceed 1.5 meters.
3. grounding lines should be short, thick and straight,
so as to reduce the influence of distributed inductors on the
ability of lightning electromagnetic pulse.
Company profile
Zhejiang Thor Electric Co., Ltd is committed to meeting the requirements of the European Union’s Waste Electrical and Electronic Equipment (WEEE) directive. This directive requires producers of electrical and electronic equipment to finance the take-back for re-use or recycling of their products placed on the EU market after 2005.
