     ● Standard: IEC60269-6:2010;GB/T13539.6-2013

       Certification: TUV; CE

 ● Main Purpose

  Applicable in the circuit of rated voltage up to DC1000V and rated current 2A-20A and rated current breaking capacity up to 20KA for the purpose of short-circuit and over-load protection of PV power generating devices and other semiconductor devices. The fuses are used in combiner box of solar PV system.

     Corrected value of operating current at different ambient temperature

            At ambient temperature 20℃, we suggest the actual operating current of fuse link not exceed rated current value. As for fuse selection, take into consideration the environmental and operating conditions, such as closing degree, air flow, connecting cable size, length, cross sectional area and instantaneous peak values and etc. The current carrying capacity test of fuse link is conducted at the ambient temperature 20℃, and will be affected by temperature change in actual operation. The higher the ambient temperature is, the higher the operating temperature of fuse link gets, and the shorter the service life becomes. On the contrary, working at a lower temperature will extend the life of fuse link.
