[Current limiting fuse]XRNT-35KV High voltage current limiting fuse

2026-6-20 13:16:13

Normal working conditions of XRNT-35KV high-voltage current limiting fuse:

Environmental temperature: The upper limit should not exceed+40 ��, the lower limit should not be lower than -25 ��, and the average temperature measured over 24 hours should not exceed+35 ��.
Altitude: The installation site has an altitude of no more than 1000m.
Atmospheric conditions: The average relative humidity measured within 24 hours shall not exceed 95%. And taking into account the condensation caused by temperature changes. The surrounding air is not affected by dust, smoke, corrosive or flammable gases, water vapor, or excessive pollution.

Application and scope of XRNT-35KV high-voltage current limiting fuse:
This product is suitable for indoor and outdoor AC 50Hz systems with a rated voltage of 12kV. It serves as a protective component for transformers and other power equipment against overload or short circuit.

Structure and working principle of XRNT-35KV high-voltage current limiting fuse:
A fuse is composed of a base, fuse tube, melt, impactor, filler, etc. The base is connected to external wires and forms an insertion structure with the fuse contacts, making it easy to replace.
High voltage current limiting fuses are used for full range protection, which can reliably break all fault currents between the current causing melt melting and the rated breaking current. They utilize the high breaking capacity of current limiting fuses, rather than the good small current overload protection characteristics of non current limiting fuses. By combining the breaking characteristics of two types of fuses and combining them into one, they complement each other's strengths and weaknesses, and obtain good protection characteristics for full range breaking.

Basic parameters of XRNT-35KV high-voltage current limiting fuse:
The basic parameters of the fuse are shown in Table 1 and Table 1

[Current limiting fuse]{{EN_0} �� - High voltage current limiting fuse for full range protection

2026-6-20 13:11:49

XRN �� - High voltage current limiting fuse for full range protection is a new type of high voltage current limiting fuse that utilizes the high breaking capacity of current limiting fuses and the good low overload fault current breaking capacity of non current limiting fuses. By combining them together and complementing each other's strengths and weaknesses, it achieves good protection characteristics for full range breaking.
