Класс B & C скачок напряжения защитник

Product introduction: class B&C power surge protector is designed for protection of low-voltage 3-phase power supply systems installations against surges,even at direct lightning storks,usually installted at lightning protection zone 0A-2.By using LTR energy control technology, it can fulfill class protection in the same place.This is of particular advantage when it is not impossible to install class and class separated by a conductor length of at least 10 m.(spd) high discharge capacity, owning CE certificate.low voltage protection levelHigh speed response Easy for mounting ,apply in IT/TT/TN systemMounting with standard modularizeOperating state indicatorInner over-thermal breakerInner circuit over-currentRemote control interface Must be connected in series in a spsce- and cost-saving way up to nominal current 125A or REP-FB-1 Technical parameter Model NumberREP-MPJ25Nominal voltage UnAC380V/50HzMax.continuous voltage UcAC 385VVoltage protection level UP≤900VImpulse current Iimp(10/350μS)25KAFollow current extinguishing capacibility (Uc)If≤1.5KArmsResponse time tA≤25 nsMax. backup fuse125A or REP-FB-IConnectorparallelinstallation35mm standard rail (EN50022/DIN46277-3)Degree of protectionIP20Cross-sectional area(max)25mm2(L/N) 35mm2(PE)Enclosure materialUL94V -0dimension11 standard modulus,DIN 43880197×89×63 mmInstallation placeclassB+classCStandardIEC 61643,GB18802-2002,GB503432004 Note: For general parameter, we can make as customers' request.
