HRC fuse electrical NT1 Knife Fuse Base Ceramic NH / NT Fuse holder ( CE ) gG / gL AC 500 / 660V 4 - 800A
This series fuse is suitable for AC 45 ~ 62 Hz, rated voltage to 1140V, rated current to 1250A. It is mainly used in the electric installation for protecting circuit from overload and short circuit ( gG / GL ); it also may derive for protecting the semiconductor device and others complete set installment from short - circuit ( aR ) as well as the electric motor from short - circuit (aM).
The rated breaking capability for this series fuse is to 120kA.
This series fuse comforms to national standard GB 13539.1 - 2008 / iec 60269 - 1:2006, GB13539.2-2008/IEC60269-2:2006 and Inernational electrical committee standard.
The variable cross - section fuse body made by pure copper / silver piece ( or silver wire ) is sealed in the fusion tube which is made by the high strength porcelain; there is full of the high - purity quartz sand processed after chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably connect with the end plate ( or junction panel ) and to form the knife shape contact insert type structure. The fuse may have fuse indiator or striker, when the fuse element fusing it can demonstrate fusing ( indicator ) or transforms each kind of signal as well as automatic transfer circuit ( striker ).
