■短路通斷特性 interrupting rating of short circuit
如圖3，將K、K1、K2閉合被測元件應立即熔斷，元件表面標識清楚，6A空氣開關K不動作。
drawing 3，Within overload circuit(K1,K2 bith be on),resistance values shall be fused immediately, Within fusing 6A air switch shall be no response and no obvious detonation and flame in fusing.
■耐沖擊性能
如圖3，閉合空氣開關K，斷開K2，將K1反復通斷30次，電阻不開路。
drawing 3，Impulsing through 30 times continuously(K2 off,K1 on),resistors shall be no disconnection
