What type of fuse protects GT and GT and ST time?

• A. C fuse
• B. D fuse
• C. E fuse
• D. F fuse

Answer: (C)

The correct answer is E fuse, which is specifically designed to provide protection for generators and transformers, as well as for certain types of time-delay applications. E fuses are particularly suited for situations where there is a need to handle inrush currents associated with inductive loads, such as motors and transformers. In applications involving generators and transformers, it's crucial to avoid nuisance tripping while still providing adequate protection against overloads and short circuits. The E fuse achieves this balance effectively, ensuring that the sensitive equipment can operate reliably without unnecessary interruptions. When considering the other types of fuses, the C fuse and D fuse typically provide protection for circuits with lower current ratings and are not optimized for the specific demands of GT (generator transformers) or ST (service transformers) applications. The F fuse, while providing a higher current rating, may not offer the appropriate time-delay characteristics required for handling the inrush current in generator and transformer setups effectively. Therefore, the E fuse is the most appropriate choice for protecting GT and ST time.
