IBD fuses are designed for the protection of HV/LV distribution transformers. The fuse technology is known
as “enclosed” melting. It ensures against any visible evidence of the fuse during its operation.
The main features include:
• enameled ceramic housing
• nickle-plated brass end caps
• solid silver fuse elements
• waterproof system for outdoor use.
IBD fuses satisfy existing operational constraints for electric networks.
Their characteristics are based on operation at ambient temperatures ranging from -25°c to +40°c, and a
maximum altitude of 1000 meters
