Product Details
High-Voltage Cut-Out Switches are used to protect equipment from overcurrent due to short circuit or ground accidents or overload. They are installed on the primary side of a current transformer or main units. When a fault current flows, the fuse link gets blown and produces arc heat which causes the material of the inner wall of the fuse barrel to disassemble and create insulating gas. This product controls the arc and blocks the fault current.
