General
YCS7N series Surge Protection Device is suitable for TT, IT, TN-S, TN-C and TN-C-S, the power supply system with the rated voltage up to 230/400V andAC 50/60Hz.
Its design corresponds to IEC61643-1. The product is usually installed in the incoming line low voltage distribution box of the building, and it can release 80kA lightning stroke current.
Feature
1. Installation
• The surge protector's housing size meets the space saving18mm width modulus re- quirement,so the device is easy to install.The lightning arrester can be easily installed by attaching it to the 35mm guide rail.
2. Characteristics
• Seal structure design, no arc leakage during operation;
• Modular design, integrated design, more beautiful appearance;
• Limp12.5kA,15kA,fast response time;
• Imported high energy graphite, stable performance, safe use;
• 35mm standard rail installation.
3. the use of advantages
• Switch type modular surge protector, with high lightning current discharge capacity;
• The unique use of sealed design structure, even in the operation, there will be no leak- age arc;
• The use of high safety, no continuous flow;
• No grounding jumper,more convenient installation, more safe;
• When used with the post-stage voltage limiting typesurge arrester, the two-stage surge arrester can be installedtogether.
Operating Conditions
1. It is needless to adjust the protection device after it has been mounted.
2. Only the protection device is installed appropriately, it can protect the poer grid automati- cally at once;
3. When the protection device is operating,the tablet ot module shall be examined regularly, to check if it glows,meanwhile,observe if the red indicator lamp of fuse brightens. Please change the fault element in time.
