The HFSC-1 Drop Out Fuse Cutout is a high-voltage outdoor protection device designed for overhead distribution systems. It provides reliable protection for transformers and power lines by interrupting fault currents caused by overloads or short circuits, while also serving as an isolation point for maintenance operations.
Designed for outdoor overhead distribution networks.
Provides dependable protection against overload and short-circuit faults.
Combines protection and isolation functions in one device.
Strong mechanical structure suitable for harsh weather conditions.
High electrical performance with stable operation.
Easy manual operation using insulated tools.
Visible drop-out indication after fuse operation.
Rated Voltage: Typically 10kV–15kV (application dependent)
Rated Current: 100A / 200A / 300A options available
Standard: IEC 60282-2 or equivalent utility standards
Structure: Insulator base, fuse carrier, and contact assembly
Installation Type: Pole-mounted outdoor application
Distribution transformers protection
Overhead power distribution lines
Utility substations and feeder systems
Rural and urban power networks
Industrial and infrastructure power systems
Maintenance isolation and switching operations
Under normal operation, the fuse element maintains a closed circuit.
When a fault occurs, the fuse link melts due to excess current.
The arc is safely extinguished within the fuse tube.
The fuse holder drops open, providing a clear visual indication of fault interruption.
Reliable protection for electrical distribution equipment.
Clear visual indication of fault operation.
Enhances system safety and operational reliability.
Durable design for long-term outdoor use.
Simple installation and low maintenance requirements.
Manufactured under strict quality control systems.
Tested for electrical safety and mechanical strength.
Designed to comply with international utility standards.
Ensures consistent and dependable performance in field conditions.
