MV Sparkless Fuses 11-22kV

Safety Benefits

• Silent interruption - no gas, sparks, or debris emitted
• Significant fire risk reduction - perfect for preventing wildfires in dry or drought-stricken areas
• Significant vegetation maintenance reduction - eliminates the need to maintain mowed grass radius beneath poles
• Increased safety to line personnel during circuit re-energising operation
• Simplified fault location with Drop-open design

Standards

• IEC 60282-1(2009) High voltage fuses, current limiting fuses
• KS C 4612 High voltage current limiting fuse

Application Locations

• Feeder circuits
• Metal-enclosed switchgear
• Overhead capacitor racks
• Power Transformers, Distributions Transformers, Potential Transformers and Station Service Transformers

Features

• Universal fit design makes for an easy retrofit into industry standard 125kV BIL and 150kV BIL interchangeable cutouts
• No special tools required - Easy installation from the ground using hotstick
• No arc and no explosion noise
• High breaking reliability and high-speed breaking possible (within 0.5 cycles)
