Three-phase power surge protection device has remote signal
function
Brief introduction
Surge protector, also called lightning arrester, is an electronic
device that provides security protection for all kinds of
electronic devices, instruments and communication lines. When the
peak current or voltage is suddenly produced in the electrical
circuit or communication line because of the external interference,
the surge protector can guide the shunt in very short time, thus
avoiding the damage of the surge to other equipment in the circuit.
Use of attention
1. surge protector is installed with 35MM standard guide rail
2. determine the discharge current path
3. the wire that marks the extra voltage drop caused by the device
terminal.
4. in order to avoid unnecessary induction loops, we should mark
the PE conductor of each device.
Product features
1. multi-functional overvoltage protection, lightning and
overpressure are no longer afraid of disasters.
2. the speed of response is 0.001 seconds, and the voltage is
controlled in the range that the equipment can withstand.
3. low output residual pressure to further ensure safety
4. traffic flow to further improve safety
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
The function of the surge protector is to limit the transient
overvoltage to the power line and the signal transmission line
within the voltage range that the equipment or system can bear, or
to inflow the powerful lightning discharge into the ground, and to
protect the protected equipment or system from being damaged by the
impact.
