Fuse Bases For Square Pipe Fuses With Knife Contacts

Applications

• Supporters for NH000-NH4 fuses of all kinds (gG, aM, aR) in electric lines (type gG), capable of working under the heat caused by rated current and prospective short-circuit impacting current up to 120KA.
• Rated insulate voltage up to 660V; Working frequency 50HzAC; Rated current 1000A. Compliant with GB13539 and IEC269.

Design Features

• The bases are made up of high-density ceramic, heat-resistant resin board and wedge-shaped static contacts in a open structure. The product is featured with good heat sinking, high mechanic density, reliable connection and simple operation. It is available for all NH000~NH4 fuses.
