1. Introduction

Solar fuse is applicable to the circuit with rated voltage to DC1000V, rated current of 1a-30a and rated breaking capacity to 20kA. It is mainly used in the combiner box of solar photovoltaic system as the short-circuit and overload protection of photovoltaic generator and other semiconductor equipment.

5. Current correction value under different ambient temperature
At the ambient temperature of 20 ℃, we recommend that the actual working current of the fuse link should not exceed the rated current value. When selecting the fuse link, the environment and working conditions shall be taken into consideration, such as the change of sealing degree, air flow, connecting cable size (length, section), instantaneous peak value, etc.; the current carrying capacity test of the fuse link is carried out under the ambient temperature of 20 ℃, and the actual use is affected by the change of the ambient temperature. The higher the ambient temperature, the higher the working temperature of the fuse link, and the shorter its service life. On the contrary, operation at lower temperature will prolong the life of fuse link.

Typical effect of ambient temperature on current carrying capacity

For example, when the ambient temperature of a certain application is 20 ℃, the rated current of the "gPV" fuse link is selected as in = 16A. Now, when the above fuse link is used in the high temperature environment of 70 ℃, the working current must be reduced additionally. The curve a above shows that the percentage of the rated value of the operation at 70 ℃ is 0.78. To ensure that the fuse link does not misoperate, the rated current value of the fuse link should be re selected. : in = 16A / 0.78 = 20.512a; select in = 20A according to the standard current level of fuse link.

Note: the curve line is the "gPV" fuse link curve for protection.
