引用第3楼martin_chiu于2010-01-12 11:22发表的 :5 ^! k# L- v( v }7 ~* x+ R
Output current, Apparent power and Current rating of overcurrent protective device,3 K( M4 k/ U% h# K

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.0 t3 V9 m5 Z* R# i3 X( P+ a
