คุณสมบัติผลิตภัณฑ์

1. SPD built-in disengager, when SPD due to overheating, breakdown failure, disengager can automatically from the grid, and give the indication signal. When SPD is working normally, the visual window will display green, and red will be displayed after failure separation.

2. 1p + N, 2p + N, 3P + n SPD consists of 1p, 2p, 3P SPD + NPE zero ground protection module, which is applied to TN-S, TN-C-S and other power supply systems.

3. 35mm standard guide rail is used for installation, and the copper multi strand conductor is 2.5 ~ 35mm ~ 2.

4. The front end of each pole of SPD must be equipped with a fuse circuit or SPD protection of lightning current of miniature circuit breaker for short circuit protection after SPD breakdown.

63. When the melt is burnt out under short circuit, the sound is very loud, the melting part is big, and there is burning phenomenon in the melting tube. According to the cause of fusing, find out the fault point and remove it.

64. When changing the melt, the specification of melt should be suitable for the nature of load and line current.

65.When replacing the melt, the power must be cut off for replacement to prevent electric shock.

66. Our experts have rich experience in various fields, so we have to provide a wide range of professional solutions for customers in various industries to win competitive advantages for customers.

คำถามที่พบบ่อย

Q1: Why is the surge light on?

A1: The surge light means that the surge protector is functioning and ready to protect. If this light goes out you know you have experienced a surge and the surge protector will no longer protect. The ground light means the surge protector is connected to a proper ground.

Q2: Do appliances need surge protectors?

A2: However, surge protectors are a good idea if you have an off-grid power system or use a generator. These are much more prone to sudden surges, so surge protectors are needed, especially with appliances that are more sensitive to surges, such as computers and medical equipment like CPAP machines.

Q3: How do I protect my fridge from power surges?

A3: The Appliance Surge Protector CSP100R offers vital surge protection for refrigerators and freezers. It prevents spikes in energy caused by storms and electrical power surges from reaching your equipment. The CSP100R provides 900 joules of protection, a surge-protected outlet and a wall tap plug.

Q4: What can a power surge damage?

A4: When a significant power surge occurs, and the electrical pressure exceeds 169 volts, it can cause the connected device and/or wiring to overheat. While smaller surges won’t cause the connected components to overheat, the excessive strain caused on the device can, over time, cause it to wear out prematurely.

Q5: Why is half my house without power?

A5: Circuit panel. Look for a breaker that is either off, or partially off, then push it all the way off, then back on. Ah, so, in most cases, if some, but not all, of your houses/apartments power is out, you have most likely tripped a breaker. … If should reset the part of the house without power.
