5.電氣特性：

5.Charctcristics of Electrical Appliancos

5.1負載容量：額定電流測100%，能繼續通電無任何熔化現象。

5.1Loading Capacity The Listed Electrical.(Included) add 100% for following,add it’s available to let current kurrcnt keep on flowing without any melding。

5.2溫度特性：進行上項測試1½小時，後繼續維持原加之電流，每隔十分鐘測試一次，連續測三次，溫度不得升高，若使用熱偶式測量方法（Tbermocouple mcthod）則本體溫升在70℃以下，若使用溫度計測量方法（Tbermocouple mcthod）則在50℃以下。

5.2Tcmpcraturc:proceed the prcceding test for 1½hours,keep testing it with the original current every 10 minutes.Continue to test it for 3 times.The temperature is not allowed to be higher The main temperalurc is below 70℃by way of Thermocouple Method while it keeps below  

   50℃by way of Thermometer Mcthod.。

5.3電阻測量：調整保險絲之額定電流值達10%時，在保險絲兩端使用高阻*電壓表測量降壓值，以電腦電阻值或電橋方式測量（額定電流2½安培（含）以上者，無須測量電阻值）。

5.3Resistance Measuring:Adjust the fuse upto 10% more than listed electrical current the 10%,we mcasure on two ends of the fuse with high voltage meter,and caculare the resistance value with elec-trical brige way.(If the listed currecct equal or more the 2½ Amp,it’s not necessary to measure the resistance value. )

5.4過載熔斷：当通过額定電流值達275%時應於10秒钟內熔斷，並於熔斷後繼續加壓於5分鐘，不得發生任何電擊現象。请参照下表。

5.4 Mclting duo to overloading:When overloading is more than275%of listed electrical current, it will be melted within10seconds,we should keep on adding voltage for 5 minutes,and can’t have any electric beating.Details as follows Table.
