Designed to protect low-voltage devices from overvoltage damage in the power grid, which may occur due to phase imbalance, a break in the neutral wire, as well as an overvoltage surge caused by lightning strikes into the power line or from damage to linear transformers. The response time is 25ns. Used in SPD Class III (Class C) to protect various power supply systems. Designed in accordance with GB 18802.1-2011/IEC61643-1: 1998-02.
The principle of operation is based on "short-circuiting" the voltage in the controlled circuit when the permissible limit is exceeded. This prevents high voltage from entering the protected section of the network. Rated operating voltage 220 volts, maximum operating voltage 320 volts. Nominal discharge current 10,000 Amperes. The maximum discharge current is 20,000 Amperes. Circuit breaker 16-25 Am.
Верно. Все варианты подключения устройств подразумевают наличие заземления. Вот документ. Без заземленя хоть как-то защитить нагрузку может только серия TAxxA2N - это варистор между N и L, и разрядник в цепи заземления. Будет работать только половинка с варистором. У остальных серий устройств ключевая роль отводится именно заземлению.
