Electrical appliances with a compressor load switch-fuse combination are appropriate for three-phase power distribution systems operating at 12 kV or less. They can be used to control and safeguard power equipment, including transformers, cables, overhead lines, and other equipment. They are particularly well-suited for use in box-type substations and the terminal substations of both urban and rural power grids. Additionally, it works well with double radiation power supply units and ring networks for safety and control.
