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.
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

Q1: Selection of surge protector
Al: The level of surge protector (commonly known as lightning protection) is evaluated based on the IEC61024 subdivision lightning protection theory installed at the junction of the partition. The technical requirements and functions are different. The first level lightning protection device is installed between zones 0-1, and the flow requirements are very high. The minimum requirement of GB50057 is 12.5 ka (10/350), and the second and third levels are installed between 1-2 and. 2-3 areas, mainly to suppress overvoltage.
Q2: Are you a lightning protector factory or a lightning protector from a trading company?
A2: We are a manufacturer of lightning surge protectors.
Q3: Warranty and return?
A3: 1. Lightning surge protector products and accessories have been tested 3 times before leaving the factory. 2. We have the best after-sales service team. If there is any problem, our team will do our best to solve it for you.
Q4: How to get some samples of surge protector?
A4: We are honored to provide you with samples of lightning protection devices. Please contact our staff and leave detailed contact information. We guarantee to keep your information confidential.
Q5: Can samples be obtained for free?
A5: Samples are available, but the sample cost should be paid by you. Sample fees will be refunded after further ordering.
Q6: Do you accept customized orders?
A6: Yes.
Q7: When is the entrusted time?
A7: It usually takes 7-15 days to confirm payment after LY, but the specific time should be based on the order quantity
