V2T-12,5/50
Transitory, single phase, Class I+II
Description
Protector of permanent overvoltages caused by increases in the network voltage, and of transient overvoltages caused by lightning strikes or network switching, in three phase installations.
In the event of a transient overvoltage, the equipment absorbs it by deriving it to earth (PE), thus preventing it from producing any damage to the devices connected to the network.
If due to an overvoltage, the protection will be inoperative, the equipment will show the warning window in red. In such a case, the protection module will have become inoperative, and must be replaced by another, pluggable and easy to replace.
This equipment DOES NOT PROTECT against voltage surges PERMANENTS.
