Fuse Links NH Series Low Voltage H.R.C Fuse Links

Fuse Links NH Series Low Voltage H.R.C Fuse Links Application This fuse series apply to AC 50Hz,rated voltage to 1140V and rate current to 1250A. It is mainly used for overload and short circuit protection in electrical devices. It can break any current during the minimum melting current to 120kA reliably, and also be derived for semiconductor devices. Its complete sets of equipment of short circuit protection(aR) and motor short circuit protection(aM).Technical Parameter Model NameNH fuseStandardIEC60269Rated current In(A)4~100AmpRated voltage Un(V)500V 660vFrequency of coil50Hz, 60Hz, 50/60HzTypesaR aMFeatures ●Variable cross-section fuse element made from pure copper or silver sealed in cardge made from high-duty ceramic.●Fuse tube filled with chemically treated high-purity quartz sand as arc-extinguishing medium.●Dot-welding of fuse element ends to the terminals ensures reliable electric connection and forms insert knife type contacts.●Indicator or striker may be attached to the fuse link to show cutout of fuse or to give various signals and to cut the circuit automatically.Applicable Working Ambient temperature-5~+40℃ , the average value cannot exceed to +35℃  within 24hAltitude2,000mRelative humidity95%Pollution levelII.Installation locationMount on the place where has no obvious vibration or impact
