Description
Interrupteur différentiel 4 pôles Ex9L-N 63 A type B 300mA 10kA
•Les Atouts de l'article:
Residual current circuit breakers B type Ex9LB63 are suitable for domestic as well as industrial applications,where are used frequency inveters, PV plant, EV chargers and similar elements. B type provides a sensitivityto residual AC, pulsating and smooth DC current, together with high frequencies up to 1 kHz.They are based on electronic technology, which brings advantages of more accurate measuring of residualcurrent and, as a consequence, reduction of unwanted tripping. These devices also do not suffer with magnetizationof the tripping unit. Thus, there is no mandatory testing period, but they must be tested regularly.On this testing period local law or regulations may apply. Recommend is to test it every 6 months in fair enviromentand every month in heavy condition.
