HFSC-30F Drop Out Fuse Cutout

● Loadbreak function permits safe disconnection of live circuits under normal load conditions
● Premium conductive materials, including silver-plated copper, maximize current transfer efficiency and resist oxidation
● Polymer insulator selection reduces overall weight and delivers outstanding hydrophobic performance in wet or polluted settings
● Configurable spare parts and mounting options simplify on-site assembly and maintenance
● International standard compliance guarantees consistent performance and broad market acceptance

◆ 24–27kV overhead distribution feeders
◆ Transformer and capacitor bank overcurrent safeguarding
◆ Utility substation and distribution line protection
◆ Industrial plants and commercial power supply networks
◆ Outdoor installations up to 1000 meters altitude with Pollution Level II conditions

A dual bearing configuration forms the backbone of the cutout's mechanical design. The main bearing provides primary support and alignment for the fuse tube, while the secondary bearing reinforces structural integrity and ensures consistent contact pressure throughout switching and fault-clearing sequences.

The HFSC-30F ships with a full complement of accessories engineered for safe operation and easy upkeep. A lower general bearing offers firm support and guided tube drop-out, while the arc extinguishing housing swiftly contains and quenches fault arcs. An American type fusible load featuring an integrated knife blade enables load-breaking and visible circuit isolation, and the 300A fusible load assures reliable interruption under high-current demands.
