I160-160A

备注：:当电流大于160A时,需外配电流互感器，

在电流规格中直接注明电流变比即可

例如：电机为90KW,额定电流为180A,需在外部配置200/5电流互感器，

此时在电流规格中注明200/5即可

Note: : when the current is larger than 160A, need outside CT,

directly indicate CT variable ratio in the current specifications

For example: the 90KW motor rated current is 180A,  need outside CT 200/5 , 

 indicate CT variable ratio 200/5 in current specifications
