Output current, Apparent power and Current rating of overcurrent protective device,
7 z5 _5 h* \# b2 p6 B" O- e7 ?都是要符合的,. j, {# P* H/ L) } i/ X
% Y7 O) s! d7 I% K
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
# W- V: C1 ~. O q( S(此部分通常都會用fuse 的rating)
6 }% f+ L' S5 C* \# U0 k7 v) T& N1 @' m" C, u/ R
9 @% k3 U) q4 C. m" G* }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./ ~- q! H5 b3 u9 E/ z3 c K) [( G
