Special Fuse-Links oiltight

Product catalog summary
Overview: This document is a technical catalogue from SIBA GmbH, detailing special oil-tight fuse-links designed for use in oil transformers. The catalogue provides specifications, applications, and technical data for these fuse-links.
Specifications: The fuse-links are designed for a rated voltage of 24 kV with a standard length of 360 mm. They are available with both ends having female threads and can be ordered with or without a striker pin. The catalogue lists various rated currents ranging from 6.3 A to 125 A.
Technical Data: The document includes detailed technical data such as rated breaking current, minimal breaking current, pre-arcing I2t value, total I2t value, and power loss for each rated current. For example, a fuse-link with a rated current of 6.3 A has a rated breaking current of 30 kA and a power loss of 16 W.
Applications: These fuse-links are specifically designed for installation in oil transformers, providing reliable protection by interrupting excessive currents.
Time-Current Characteristics: The document includes time-current characteristic curves, illustrating the relationship between time and current for different rated currents. These curves help in understanding the performance of the fuse-links under various fault conditions.
Key Features: The fuse-links are oil-tight, ensuring safe operation within oil-filled transformers. They are compliant with IEC 60282-1 standards, ensuring high reliability and safety.
