2012 New Outdoor Porcelain 12kV Cutout Fuse

1.Rated voltage:12kV/11kV 2:Rated current:100 or 200A 3.Porcelain insulator 4.125kV BIL 5.Dropout fuse cutout 12kv 100a 200a

Description

1. The cutout body, an open "C"-shaped frame that supports the "fuse holder" and a porcelain insulator that electrically isolates the conductive portions of the assembly from the support to which the insulator is fastened.

2. The fuse tube, which contains the interchangeable fuse element and also acts as a simple knife switch. When the contained fuse operates or blows, the fuse holder will drop open, disengaging the knife switch, and hang from a hinge assembly. This hanging fuse holder provides a visible indication that the fuse has operated and assurance that the down-stream circuit is electrically isolated.

3. The fuse element, or "fuse link", is the replaceable portion of the assembly that operates due to high electrical currents 

4. The fuse elements, or fuse links used in most distribution cutouts are tin or silver alloy fuse links that melt (or operate) when exposed to high current conditions. The ampere ratings of fuse elements rated from 100 ampere to 200 amperes.
