SSD 50X/80/160

Short Description:

At  present,the  front  end  of  the  lightning  protection  device  is  mainly  equipped

with  a  small  plastic-case  circuit  breaker  or  fuse, and  is  not  equipped  with  SPD

Specific  Disconnector,when  lightning  strikes,due  to  the  structural  limitations  of

the  circuit  breaker, resulting  in  lightning  residual  voltage  is  very  large,it  is  easy

to  damage the  back-end  equipment,and  easy to  cause  circuit  breaker trip.The  other

case,the  rated  frequency  current  of  the  circuit  breaker  is  very  large,and  trip  current

far  exceeds  the  rated  current, Power  frequency   continuous  flow   can’t  cut  off,easy  to

cause  fire,then   it   is  necessary  to  be  equipped  with   the  SPD  Specific Disconnector

to  solve  the  above  problem
