YCHGL series load isolation switches (hereinafter referred to as switches)are suitable forAC 50Hz,rated voltage 660V,and rated current up to 3200A.They are used for infrequentconnection and disconnection of circuits and electrical isolaion.This product adopts a mod-ular design structure and has flexible and diverse combinations.Switches are widely usedin distribution systems and automation systems in construction,power,petroleum,chemical,and other industries.

Standard:IEC60947-3

AC 50Hz, rated voltage 660V, rated current 3200A. It is used for making and breaking circuit not frequently.

Standard: IEC60947-3

YCH5 series vertical fuse-switch disconnector is applicable in the circuit of rated voltage AC690V and below, rated current AC 160A-630A, rated frequency of 50Hz.
YCH5 series are infrequently manually operated multipolar fuse combination switches.
They break or switch off on load and provide safely isolation and protection against overcurrent for any voltage electrical circuit.
Standard: IEC 60947-3.
