Our export volume exceeded $20million in 2011, a 15 percent increase from the previous year.In 2011 we got VDE testing and certification institute as registered manufacturer’s laboratory.

Fuse Selection Flow

　　1.Safety approval:According to the certification required on the end product to determine the fuse safety approval.Such as UL standard or IEC standard.
　　2.Physical dimension:According to the space limit of circuit in design to decide,such as length,diameter,lead type,etc.
　　3.Voltage rating:the voltage rating of the fuse shall be greater than or equal to the available circuit voltage.Such as 24V,32V,63V,
125V,250V,etc.
　　4.Interrupting rating:The interrupting rating of the fuse shall be greater than the Maximum Fault Current of the circuit.
　　5.Current rating:Select as follows:
　　(1)When selecting a fuse at 25℃ ambient
　　The current rating of UL standard fuse ≥normal flow current/0.75
　　The current rating of IEC standard fuse ≥normal flow current/0.9
　　(2)Ambient temperature:The current carrying capacity test of a fuse if performed at 25℃ ambient.The higher The ambient temperture is,the shorter fuse life will be and the lower the current carrying capacity will be.So the ambient temperture shall be considered when selecting a fuse.Refer to the following chart showing the effect on the carrying capacity :

(3)Pulse:pulse produces thermal cycling and mechanical fatigue which could affect the life of fuse. In design considering the pulse factor,the Pulse I2T should less than the fuse I2T value.
The fuse I2T >the pulse I2T/Pf
Pf : the pulse factor,it will change according to endurable times of pulse shock.The date is as follows :

6.Testing
　　The selected sample must be tested in the actual circuit to verify the suitability of the selection.This testing should include the normal and fault conditions testing to ensure that the fuse can operate properly in the circuit.
