Fuseless Capacitor
Eaton’s Cooper fuseless capacitors feature a rated voltage of 2.4-22.8kV, a capacity of 50-500kVAr, no internal fuses, losses $\leq$ 0.07 W/kVAr, stainless steel enclosures, Edisol oil insulation, compliance with IEC 60871-1 standards, and type-testing at ASTA Lab (STL).
In electrical systems, maintaining an ideal power factor and voltage stability is critical to ensuring operational efficiency, energy savings, and extended equipment lifespan. One of the most common, highly effective, and widely adopted solutions is the use of capacitor banks

Impressive Specifications of Lead-Free Capacitor Banks
Key Features:
- Technical Specifications: EX-7L Fuseless Capacitor
Design: Fuseless design (No internal fuses).
Bushings: 1 or 2 bushings.
Internal Discharge Resistors: Designed to reduce terminal voltage to 50V within 5 minutes or 75V within 10 minutes after disconnection.
Low Losses: Total losses are remarkably low ($\leq$ 0.07 W/kVAR).
Terminals: Hermetically sealed terminals with high mechanical strength.
Insulating Dielectric: Edisol fluid, Non-PCB (environmentally friendly).
Applications: The EX-7L capacitor is ideal for use in fuseless capacitor banks or externally fused capacitor bank configurations. - Unlike traditional capacitors, lead-free capacitor banks are designed without internal fuses. This design enhances reliability, minimizes the risk of explosion during faults, and simplifies the protection system for easier maintenance. Furthermore, it is perfectly suited for both externally fused and fuseless capacitor bank configurations.
- A wide operating voltage range from 2.4kV to 22.8kV, combined with power ratings from 50kVAR to 500kVAR (or higher), makes lead-free capacitors ideal for various compensation station models, ranging from individual units to complex banks. The product supports seamless system scalability without impacting the existing architecture.
- Fuseless capacitors offer various Basic Insulation Levels (BIL) ranging from 75kV to 200kV, tailored to specific voltage levels and required protection standards. This enhances the system’s resilience against sudden voltage surges, particularly in high-lightning frequency environments or unstable electrical grids.
- Fuseless capacitors are engineered with corrosion-resistant stainless steel enclosures and hermetically sealed terminals, enabling them to withstand vibrations, mechanical impacts, and extreme weather conditions. They are specifically designed for outdoor installations in humid tropical climates, dusty areas, or harsh industrial environments.
- The product has undergone type testing at ASTA Lab (STL), one of the world’s most prestigious testing facilities. Compliance with the IEC 60871-1 standard ensures dielectric stability, operational safety, and exceptional durability, making the equipment fully qualified for major domestic and international projects
Practical Applications
Fuseless capacitors are widely applied in systems requiring reactive power compensation, power factor ($cos \phi$) improvement, voltage stabilization, and reduction of line losses:
- Transformer Substations (Fixed or Automatic Reactive Power Compensation Banks)
- Power Distribution Systems for Industrial Parks
- Manufacturing plants with heavy inductive loads (motors, press machines, industrial chillers
- High-rise buildings and commercial centers.
- Renewable Energy Systems (Solar Farms, Wind Farms)
- EVN Transmission and Distribution Grids or Local Power Utilities
