High voltage fuse
摘要:
A fuse is provided that is suitable for operation in unusual environments and includes an operation indicator that is simple and reliable. A movable arcing tube is released during operation. As the arcing tube moves outside the fuse assembly, a latching spring moves into a receiving groove in the arcing tube to retain the arcing tube in the external operated position.
