ISO9001 Power Surge Protection Device 20ka 40ka For Equipment Room
Surge protector, also known as lightning protection, is a variety of electronic devices, instruments, communication lines to provide safety protection of electronic devices. When the electrical circuit or communication lines because of external interference suddenly generate spikes in current or voltage, surge protector can be shunted in a very short period of time on conduction, thereby avoiding damage to other equipment in the circuit surge.
SPD is used to protect all kinds of electrical equipment in the power system from lightning over-voltage, operation over-voltage, power frequency transient over-voltage impact damage to an electrical appliance
The electrical circuit or communication lines because of outside interference peak current or voltage suddenly, the surge protector can in a very short time conducting shunt, so as to avoid damage to other equipment surge in the loop Installed front of inverter input and back of inverter output Installed in Parallel the spd is installed in the electric circuit with parallel, the first to play a protective role, the response time in the 25 to 50 nanosecond
These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions. The use of high-performance varistors permits a rapid response time and a low protection level, without any line follow current. If circumstances are uncertain and there is a risk of fire from an overload, the internal cut-off unit disconnects the arrestor from the mains if necessary. In addition, the QR code printed on the arrestor allows disary. In addition, the QR code printed on the arrestor allows direct access to the online installation instructions.

Installation requirements
Surge protector using 35MM standard rail installation
For fixed SPD, the conventional installation should follow the following steps.
1)Determine the discharge current path
(2) mark the additional voltage drop caused by the wire at the end of the equipment,.
3) To avoid unnecessary induction loops, the PE conductor of each device should be marked.
(4) the establishment of equipotential connection between the equipment and SPD.
5) To carry out energy coordination of multi-level SPD
In order to limit the protected part after installation and unprotected
