Applications

  • H1 series of fuse disconnecting switch, are mainly used in circus with high short-circuit current and motor circuit as power switch, disconnecting switch or emergency switch.
  • Rated insulation voltage up to AC 50Hz 800V; Rated working voltage up to 690V; Rated working current up to 250A; Rated short-time withstand current (valid): 20Ith/1S. The switch complies with GB14048.3 and IEC/EN60947-3.

Design Features

  • The switch with half sealed structures is made up of two parts: the seat and cover (fuse holder). Through the window in the cover, it can observe the rated data of the fuse links and indicator status.
  • The switch should be matched with the appropriate size of fuse links accordingly. H1-160/1 is single-pole and H1-160 is three-pole, both can be matched with size NH000 and NH00 fuse links, H1-250/1, H1-400/1, H1-630/1 are single-pole and H1-250, H1-400, H1-630 are three-pole, They are matched with NH1, NH2, NH3 fuse links separately. The three-pole switch can be combined with the single-pole version with the same size into four-pole switch.
  • The switch has the features of small size, reliable operation, convenient installation and removal.
  • All of these products, except for conductive parts all are the finger-touch protection: IP20.
  • Compliance with GB14048.3 and IEC/EN60947-3.
