220v appliance surge protector Low-voltage power system lightning protector
Brief introduction
The product is a surge protector for the plug type
low-voltage distribution system, including the replaceable element,
and the voltage limiting element is made up of a metal oxide
varistor in parallel. 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.
Use of attention
1. device is a series connection mode.
2. it should match the working voltage of the protected
equipment. Please install according to the installation sketch.
3. lightning protection device IN as input and OUT as
output, the input end is connected with the outside, and the output
end of the input end of the connecting device is protected.
Product features
1. able chips can react quickly when problems appear.
2. Easy to install in small size
3. cut off the line when undervoltage occurs, and reset
automatically after restoration.
Structure and Principle
SPD is a port, shocking protection, indoor-mounted installation, voltage-limited.
SPD hold disconnector inside, when SPD breakdown failure by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is working properly, visible window display green, it display red when it breakdown and disconnect.
1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground protection module, apply to TN-S, TN-C-S and other power supply system.

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.
