HR17B Isolation type knife switch melting Rated Voltage:400 Rated Breaking Capacity:100/50 Rated current of Fuse:6-100

HR17B Isolation type knife switch melting:

GHH1(HR17B)Series fuse-switch-disconnector (hereinafter referred to as switch) is the world advanced product, which conforms to IE60947-3 and GB14048 standard. It is intended for power switch, disconnector-switch, emergency switch and circuit protection in power distribution and motor circuit with high short-circuit current, whose rated insulation voltage is up to 690V, rated operating voltage is to 400V, rated operating current is to 630A and rated operating frequency is to 50Hz instead of putting on or off single electric motor directly. 

Our factory:

We produce not only the low voltage fuses but some combined electrical apparatus such as disconector-switch-fuse, ceramic lamp holder and other low voltage electric porcelians. Some products have been sold to over ten countries and areas from East South Asia and Europe. Our ceramic lamp holders came into American market in 90’s and acquired CSA Register Acceptance of America and Canada.

As the specialized factory producing low voltage screw-plug fuses appointed by mechanical industry department, we drafted JB2106 low voltage fuse standard and joined in drafting GB773 low voltage electric porcelians and GB13539 low voltage fuse National Standard and got the Technology Research Reward by Mechanical Industry Department.
