Product Description

Applications
This series fuse base is suitable for AC 50Hz,ratedinsulation voltage up to 69ov, rated current up to 630A,100mm or 185mm bus system.As a circuit overload andprotection, it is widely used in box change and cablebranch box.Products comply with GB13539.GB14048.IEC60269,IEC60947 standards.

Design Features
The product is the 3 bar fuse base mounted on the bustrack.The utility model combines 3 longitudinal arrangedunipolar fuse holders into an integral body, an electricshock (feeding, electric shock) is connected with onephase of each phase,and other contacts (output endsand contacts) are connecled with a wire connecting device.The base is made of strong fiberglass reinforced polyestermaterial. Fuse contacts and lead plate together to ensurethat the product energy consumption is small ; acceptancepower is large; low temperature rise.
