Product Description

Type RT2-20 (E), without being used with holders or clips, can be directly welded on the integrated circuit board, ceramic tube, high breaking, slow blow, lead fuse. The size is 5 x 20 ± 1.

The heat converted by the current when the fuse is energized, will make the increase of melt temperature, in the normal operating current or allowed overload current the heat generated by the current and the heat emitted by the melt, housing and surrounding environment through radiation, convection and conduction, can gradually reach equilibrium, if the heat can't keep pace with the heating speed, the heat will accumulate on the melt gradually, the melt temperature rises, once the temperature reaches the melting point, the heat will make it liquid or gas, thereby open the circuit of current, and thus safety protection to the circuit and person is achieved.

Because the product is filled with quartz sand, the melt temperature increases slowly, in the normal use of the case, the stability is higher!

 

Application: White Goods, Power Supply, Industrial Control, etc.
