各位大虾,2 Y& Z! X" Z0 h+ V
在GB 494-2001的2.6.3.2中明确说用于测试的电流额定值是取以下最小值: U1 s- y% Z0 F( I
——设备的额定电流;
- A0 | E. Y' [( a ——建筑物配线中的过流保护装置的额定值;5 }0 S6 Y j' f! I. r# P: j& H
——设备中过流保护装置的额定值。) ~( H1 T) k! S2 t& A
....... 七楼已经说得很明白了:1 Y' `1 f6 z6 B3 }- ]" {
以下是摘录标准内容,在CB报告中测试电流应该为16A的1.5倍.0 t% s/ A) G" x% r6 t
a) For PLUGGABLE EQUIPMENT TYPE A, the PROTECTIVE CURRENT RATING is the rating of an# v+ b, l7 s7 n0 h4 Z3 C: c
