4, DC Fuse Use the field

Suntree DC fuse consists essentially of a melt, a housing, and a support, where the melt is a key element in controlling the fusing characteristics. The material, size and shape of the melt determine the fusing properties.

Suntree DC Fuse with anti-delay characteristics, that is, overload current is small, fuse a long time; overload current, the fuse time is short. Therefore, in a certain overload current range, when the current back to normal, the fuse will not fuse, can continue to use. Fuses have a variety of different fuse characteristics, can be applied to different types of protection needs.

 

5, When got issue, how to check and Overhaul:

Melt blow response measures, to really analyze the reasons for the fuse, the possible reasons are:

Short circuit fault or overload operation and normal blow.

Be sure to check the N-wire in the TN grounding system, the grounding protection line of the device, and do not allow the use of fuses

When replacing the melt, it is required to:

Melt installation mechanical damage, so that the cross-sectional area becomes smaller and in operation caused by misuse.

When replacing a new melt, check that the melt rating matches the device being protected. Maintenance Check the fuse, according to safety regulations, cut off the power, do not agree to charge the fuse tube.

Check the appearance of the fuse (remove the fuse tube) with or without damage, deformation, porcelain pieces with or without flashing marks.

Clean the dust and check the contact point.

Fuses should be repaired with the power distribution unit at the same time:

Replace the new melt, to check the internal combustion of the fuse tube, if severe burns, should also change the melting tube. Filling Filler When replacing the melt, pay attention to fill the filler.

Check the fuse, the melt and the protected circuit or equipment is matched, if the problem should be investigated in time.

Before installing the new melt, find the cause of the melt fuse, not determine the cause of the fuse, do not replace the melt test.

Melt used for too long, the melt due to oxidation or high temperature during operation, so that the characteristics of the melt and error. Porcelain melting pipe damage, do not answer the application of other material tube instead.
