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
