我看了一下3.4.2的要求,有些疑问.
4 N \# v$ F. X* J, n( a" _& K: [/ u& s- I4 e9 k- `) X- n
断开装置,它有举例子说:% `; ^8 Y, E' k6 j

-a main supply plug that is of direct plug-in equipement
7 C* l2 m5 S! z6 c' y8 X-a appliance coupler,

-for a dc mains supply that is not at a hazardous voltage, a removable fuse, provided that it is accessible only to a service person
" [+ r: V* f8 i-any equivalent device.' `7 p7 d+ a/ d
关于KEVIN1946说的断开装置fuse是属于-a circuit-breaker这个类别吗? |
