Description
Ptr.Sbt.Tta.Combi 2P25T12.5/50 Iimp 12.5Ka Imax 50Ka Pmt.240V Ac Iga 2X16A 10Ka. COMBI-2PT12.5/50 2x25A protector against transient and permanent overvoltages for single-phase lines. Power supply at 240VAC. With 10kA IGA. Protector for permanent surges caused by increases in network voltage, and for transient surges caused by lightning strikes or network switching, in single-phase installations.
Details
The equipment measures the voltage in the installation permanently and detects any increase in it, greater than 10% of the nominal voltage. If this anomaly is detected, it acts on the IGA (Automatic General Switch), disconnecting the voltage in the installation. The action time will depend on the level of overvoltage detected (according to the specifications of the EN50550 Standard). The device will be operational again once it is manually reset, as long as the voltage is between its nominal values. In the event that a transient overvoltage occurs, the equipment absorbs it, diverting it to ground, thus preventing any damage to the devices connected to the network. If the protection becomes inoperative due to a transient overvoltage, the warning window will appear in red. In this case, the protective module will have been rendered useless and must be replaced with another one.
