Introduction
HY1-C series surge protective device is applicable for power distribution system of TT, IT, TN-S,TNC-C-S
whose Alternating Current is 50Hz/60Hz,400V and below.Also,it can be used for potential connection when there is lightning.
Its design conforms to the standard of IEC-61 643-1 and GB18802.1(2002),it is installed on the 35mm mounting rail.
When over-currentoe- curs and the pulse fails,the releasing device in it can be released from the electric net
autom-atically,meanwhile,the module on the viewable window can be changed when working voltage exists.
Product Characteristics
It can change the unit of the surge protection even if there has the electricity,It can sustain the inductive lightning strike to
max40kA(8/20 ~ s) Aotion response time < 25ns, The color of the viewable window shows the working status,green means
normal,red means abnorma
Installation and application
The class C SPD,used for potential connection when there is lightning,can be installed at the juncture of LPZOB or LPZ1
and LPZ2.
Generally.it is installed in power distribution case,computer center,telecommunication computer room,elevator controlling
room ,fire prevention center,self-control room in industry,control room of frequency conversion equipment,opera-ting room
in hospital,monitoring room and the power distribution case in area of electronic medical treatment equipment Also,it can
be installed in the whole power distribution case when there is no more six floors building.as for the scattered villa.the SPD
should be installed in the power distribution case in every residence.
