From the site description:
A new breakthrough in socket products, SURGE PROTECTION is a functional substitute, transient high voltage and current to 10,000V and 10,000A with star-up lapse of 1us.
It will completely restrict indoor circuit to a safe range. It has passed the test and inspection of notional specialist authority of lightning protection.
It guarantees safe operation of your any electrical equipment or devices, such as computer, telecommunication, video and audio, etc.
Response Time …………………….t-> 25nS
Varistor voltage ……………………470V –at 2mA (8/20uS)
Clamp voltage………………………800V – at 100A (8/20uS)
Max voltage………………………..1.2KV at 4.5KV (8/20uS)
Max energy absorbtion………………230j (1:1mS)
Built-in thermal circuit breaker is certified by UL and CSA, with swift response and well processing. When current is over the rating, the button of protection device skips up quickly to cut off power. After overload is eliminated, power is on by pushing down the button, restoring to normal protection condition. Not need to replace its fuse or tube is its advantage, with repeated and convenient use.
Warning:
This power board is intended for use indoors with a maximum rating of 10A/2400W of equipment. Improper use of overloading the power board may cause personal injury and damage the unit. This appliance is not intended for use by young children or infirm persons without supervision. Yong children should be supervised to ensure they do not play with the appliance.
i find they sell a lot of low quality items,not sure for this one.
