Description:

XRNM1-7.2/80 High voltage current limiting fuse is applicable to indoor AC 50Hz, rated voltage 3.6KV system. It can be used together with other protective appliances (such as switches, vacuum circuit breakers) as a protective element for overload or short circuit of high-voltage motors and other electrical equipment

XRNM1-7.2/80 High voltage current limiting fuse adopted bus type structure and the fuse is installed on the bus, which has the advantage of firm installation and good connection. The impactor is connected in parallel with the melt made of silver sheet and sealed in the melt pipe together with the chemically treated quartz sand; The fused tube is made of alumina porcelain. In case of line fault, the melt melts. At the moment of arc in the melt, the high resistance metal wire of the impactor and the melt fuse immediately in parallel, and the impactor pops up quickly to push the interlocking electrical contact, automatically switch the circuit or send a fuse signal. The high-voltage fuse has the advantages of good current limiting characteristics, fast action, no maloperation, etc.
