VCF Series 12kV Indoor Handcart Type Contactor-Fuse Unit
VCF Series 12kV Indoor Handcart Type Contactor-Fuse Unit is a compact medium-voltage switching and protection device designed for three-phase AC power systems. Combining a vacuum contactor (or circuit switching unit) with high-performance fuse protection, it provides reliable control, overload protection, and short-circuit protection for 12kV electrical applications.
Featuring a withdrawable handcart structure, the VCF Series offers flexible installation, convenient maintenance, and excellent interchangeability with compatible metal-clad switchgear systems. It is widely used in industrial plants, power stations, substations, mining facilities, and other medium-voltage systems requiring frequent switching operations, reliable protection, and safe power control.
