Kyung Dong Power Fuse are available for the source-side continuity protection against faults at the transformer, cablefeeder or capacitor bank, and transformer protection against permanent secondary faults(whether the fuse is on the primary or secondary side).
They are tested according to the latest revisions of ANSIC37.41-1998, and are also designed for sealing the fuse element against ingress of moisture, giving automatic isolation to the open position in the event of the fuse blowing.
The main characteristics are :
•Full Range Fault Protection with 3-200 Anp. Fusing.
•Full Coordination with other Protective Devices.
•Very Good Performance on Small Over-Current.
