Product Description

Product Detail:

XRNT(XDR20)-40.5 High-voltage current-limiting fuse for the wind power transformer protection, applied to ac 50 Hz, rated voltage 40.5 KV power system. As a power transformer and other electric equipment overload and short circuit protection component, mainly installed on the American box change, can box with other electrical components. When the current exceeds a predetermined value after a certain period of time, with its own heat to melt melting breaking circuit switching devices.
Construction:
The fuse consist of a fuse- link, base and fuse holder (handle), plug-in structure.
The fuse-link is cylindrical shape. It is composed of glass fiber epoxy fusion tube, contact round cap, the melt of skeleton, mica, quartz sand.Both ends of the fuse-link insert the contact column of the fuse holder, fixed with set screws and united as one piece. The base semicircle groove put O type sealing ring, plug in fuse holder which install fuse-link to base,screw on cap, insert and hold.
