Description
Protector against transientovervoltages, caused by atmospheric discharges, switching operations in electric circuits and electrostatic discharges, in three-phase installations.
In the event of a transient overvoltage, the equipment absorbs it by shunting it to ground (PE), thus preventing it from causing any damage to the devices connected to the network.
