High Voltage Current Limiting Fuses

High Voltage Current Limiting Fuses: Reliable Protection for Demanding Electrical Systems

When safeguarding high-voltage circuits from overloads and short circuits, High Voltage Current Limiting Fuses are your first line of defense. Designed for rapid fault interruption (often <10ms), these fuses prevent catastrophic damage in critical applications like electric vehicle (EV) charging stations, renewable energy systems, and industrial power grids. With over 20 years of R&D expertise, our fuses combine 500V/20kA+ breaking capacity, automotive-grade durability, and compliance with global standards like IEC 60282-1 and UL 248. Whether you’re protecting transformers or managing DC arc faults in solar farms, our solutions deliver precision and reliability.

Technical Specifications

Key Advantages

Ultra-Fast Fault Interruption

Our current-limiting fuses react within milliseconds to isolate faults, minimizing downtime and preventing cascading failures in high-voltage grids.

Built for Extreme Conditions

Engineered to withstand vibration, humidity, and temperature fluctuations (-40°C to +125°C), ideal for EVs, outdoor substations, and mining equipment.

Customizable Designs

Tailor voltage ratings (up to 145kV), current thresholds, and form factors to match your system’s needs.

Globally Certified Reliability

Compliant with IATF 16949, CE, TUV, and CCC standards, ensuring safety in automotive and renewable energy applications.

Space-Saving Efficiency
