CSP transformers are equipped with an internal _______.

Explanation:
The main idea is that CSP transformers include a protective device that will disconnect the transformer when fault current appears. An internal fuse acts as this protective element: it is designed to carry normal operating current but melt and open the circuit if a fault causes excessive current, preventing damage to the windings, core insulation, and surrounding equipment and reducing the risk of fire. The core, windings, and insulating fluid are essential parts for energy transfer and insulation/cooling, not for automatic disconnection during faults. So the fuse inside the transformer is the protective feature that makes the correct choice.
