FZN21-12d/630-20 Indoor Load Switch
Detailed Product Description
Vacuum Breaker
1.General
FZN21-12D/630-20 Indoor AC high pressure Vacuum Load Switch (called load switch for short) is used in distribution substation of industrial and mineral enterprises for cutting and closing load current, close cycle current and cable charging current .The load switch has obvious diconnection fracture,and can be euipped with relevant ground knife and electric spring mechanism for telemechanic and telecontrol.
FZN21-12D.R/125-31 combined electric appliance is applicable in distribution substation and substation of industrial and short circuit current. The operating mechanism can be either manual or electric for meeting the requirement of 3 kinds of remote control for power system.
Cited standard:
GB3804.1-90(3-63kV AC High Pressure Vacuum Load Switch)
GB16929-97(AC High Pressure Vacuum Load Switch-Fuse Combined Electric Appliance)
