■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，爆裂聲和火花小，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
