Description
Parafoudre 1 pôle Ex9UE type 3, 275 VAC, 10 kA sans signalisation
•Les Atouts de l'article:
The Ex9UE3 line is a group of Class III Surge Protective Devices. They are intended as a fi ne protection againsttransient overvoltage, installed downstream to Class II SPDs. The application fi eld of Ex9UE3 is protection ofsensitive electronics used in or close to distribution board, typically home automation, IT systems etc. The Y connectionof functional elements provides balanced protection of L and N conductor towards PE thanks to identicalMOVs for both working conductors and full isolation due to connection to PE via Spark Gap.Class III SPDs should be installed maximum 5 meters from the protected device. Coordination with Class IISPDs Ex9UE2 20 is defi ned also for near installation. To reach best parameters, it is recommended to install bothclasses with mutual distance of 5 meters of connecting cables.The design of Ex9UE3 is based on Metal Oxide Varistors. Such design provides very low response time. Themodular design with plug in inserts allows simple and quick replacement of function modules in case of MOV isbeyond if its lifespan due to often occurrence of overvoltage peaks.
