Combination Electrical Fuse Type Isolation Switch
Combination electrical - fuse type isolation switch is a simple and effective manually operated protective device, mainly used for isolating circuits or short circuit protection in circuits.
Isolation switch is a switch device mainly used for isolating power supply, switching operation, connecting and cutting off small current circuits, without arc extinguishing function.
This outdoor three phase disconnect switch is designed for medium and high voltage distribution lines, substations and outdoor switching stations. It provides a visible isolation point for maintenance, inspection and circuit sectionalizing operations, supporting safe electrical isolation in power distribution systems.
