Current limiting backup fuse
The High Voltage Current Limiting Fuse is a vital protective device for high-voltage power systems, designed to prevent damage from overloads and short circuits. By limiting fault currents and reducing the energy that passes through during a fault, these fuses help protect transformers and other high-voltage equipment.
GRL High Voltage Current Limiting Fuses are built for indoor power systems with voltages between 12kV and 24kV and rated currents up to 200A. With a high breaking capacity of up to 40kA, they ensure quick, reliable fault clearing and are essential for maintaining the safety and efficiency of electrical systems.
The current-limiting feature significantly reduces the stress on power systems, extending the life of critical equipment like transformers. Compact, durable, and reliable, our High Voltage Current Limiting Fuses provide long-lasting protection in demanding environments.

1. What is a High Voltage Current Limiting Fuse and how does it work?
A High Voltage Current Limiting Fuse is a protective device used in high-voltage systems to prevent damage caused by overloads or short circuits. It works by limiting the fault current during a fault, quickly interrupting the current, and reducing the energy let-through, which protects transformers and other high-voltage equipment from severe damage.
2. What are the typical applications of High Voltage Current Limiting Fuses?
These fuses are primarily used in indoor power systems, particularly in high-voltage networks with voltages between 12kV and 24kV. They provide protection for critical equipment such as transformers, switchgear, and distribution lines, preventing damage from overloads and short circuits.
3. What is the breaking capacity of these fuses?
Our High Voltage Current Limiting Fuses have a breaking capacity of up to 40kA. This allows them to safely interrupt fault currents as large as six times the rated current, ensuring rapid fault clearing and minimal damage to the electrical system.
4. How do High Voltage Current Limiting Fuses protect the equipment?
These fuses limit the fault current and reduce the energy let-through during a fault, which minimizes thermal and mechanical stress on the equipment. This significantly extends the lifespan of expensive electrical components like transformers and helps maintain the overall safety and efficiency of the power system.
5. Why should I choose a High Voltage Current Limiting Fuse over traditional fuses?
Unlike traditional fuses, High Voltage Current Limiting Fuses are designed to interrupt current more quickly and with greater precision. The current-limiting feature reduces the energy let-through, offering superior protection, minimizing damage, and extending the life of critical equipment. This makes them ideal for high-voltage systems where reliable protection is essential.
6. Are the High Voltage Current Limiting Fuses compliant with international standards?
Yes, our High Voltage Current Limiting Fuses meet international standards for safety and performance, ensuring reliable operation and protection in high-voltage power systems across various industries.
