Voltage: 3-40.5KV
Type: Indoor Medium voltage current limiting fuses
This product is suitable for indoor AC 50Hz, rated voltage 3.6kV, 7.2kV, 12kV, 24kV, and 40.5KV system. It can be used in conjunction with other protective appliances (such as load switch, vacuum contactor, etc.) as overload or short circuit protection for power transformers and other electrical equipment, also a necessary accessory product for high-voltage switch cabinets, ring network cabinets, and pre-assembled high-voltage and low-voltage substations.
The fuse shall be capable of interrupting any fault current between the minimum interrupting current I3 and the maximum interrupting current I1. The I3 current is approximately 4 times the rated current.
