High-voltage fuse
This product is suitable for indoor AC 50Hz systems with rated voltages of 3.6kV, 7.2kV, and 12kV. It can be used in conjunction with other protective devices (such as switches and vacuum contactors) as a protective component for overloads or short circuits in high-voltage motors and power equipment.

Note: 1. The above are the rated parameters of a single tube. According to the user's needs, a fixed structure can be used to connect the fuse elements in parallel, which can achieve high performance
Rated current value.
2. * Determined by whether an impactor is installed.
