Product Description
Product Detail
The drop out fuse 11kv also known as fused cutout switch is an essential protective device in outdoor high-voltage distribution systems. It delivers:
• Short-circuit and overload protection for transformers and branch lines
• Load current switching, enabling safe maintenance and isolation
• Visible disconnection, as the fuse switches to an open position when blown, signaling a clear fault
Application of Expulsion Fuse Cutout
Generally, fuse cut-out contains following parts:
1 Insulator;
2 Metal parts;
3 Fuse tube;
4 Fuse element link.
Connected with incoming feeder of distribution transformer or distribution lines, high-voltage drop-out fuse cut-out mainly protect transformer or lines form short circuit and overhead, and on/off loading current.
Cut out fuse is composed of insulators and fuse tube/carrier.
Static contacts are fixed on two sides of insulator support while moving contacts are installed on two ends of fuse tube/carrier. Fuse tube/carrier is composed of inner arc-extinguishing tube, outer phenolic compound paper tube or epoxy glass tube.
Typical applications:
Pole-mounted distribution transformers in 11?kV networks
Overhead distribution feeders branch lines
Rural or utility grid systems where reliable isolation is required
Why Choose Our 11?kV Drop Out Fuse
Reliable Electrical Protection
Supports 100?A and 200?A fuse links for different load requirements
High breaking capacity kA ensures effective short-circuit interruption
Designed to meet IEC?60282 2 or region-specific standards like IS 9385
High impulse withstand voltage e.g., up to 110 kV for lightning protection
Durable Construction Insulation
Available with polymeric insulator silicone / fiberglass composite for lightweight, UV and pollution resistance
Also offered with porcelain insulator for traditional robustness
All conductive parts use high-quality copper/brass; contact surfaces are silver-plated for reliable conductivity
Long Mechanical Life Safety
Mechanical life typically ? 10,000 operations in many designs
Visible drop-out of the fuse tube offers safe and instant indication of fault — supports maintenance and fault diagnostics
Large ring-pull design simplifies installation and removal for field technicians
Installation Maintenance Guidelines
Ensure the fuse tube is properly seated in the jaws and the motion indicator if any is correctly mounted.
Maintain recommended installation angle per spec sheet for reliable drop action.
Use the correct rated fuse link 100A or 200A based on coordination studies with downstream devices.
Periodically inspect and replace fuse links and tubes — particularly in polluted or corrosive environments.
