您說的item e, 是針對過電流保護裝置, 以fuse rating or 線路使用狀況下的電流 x 2 倍, 該 fuse 必須在120 秒內断開

对,我说的关键就是这句:The current ratings of overcurrent protective devices are based on fuses and circuit-breakers that break the circuit within 120 s with a current equal to 210 % of the current rating specified in the table.- U6 `; x5 z$ z/ A; }5 y
