In fuse testing, which two specific fuse types are mentioned for contact points during testing?

• A. Ferrule Fuses and Knife‑Blade Fuses
• B. Glass Fuses and Ceramic Fuses
• C. Resettable Fuses and Cartridge Fuses
• D. Time‑Delay Fuses and Fast‑Acting Fuses

Answer: (A)

In fuse testing, you want contact points that are easy and safe to probe with test equipment. Ferrule fuses and knife-blade fuses are the two styles that provide clearly exposed end-terminals designed for direct contact. Ferrule fuses have end caps with ferrule-style terminals at each end, while knife-blade fuses use two flat blade-like terminals on opposite ends. This makes it straightforward to connect measurement probes or test leads to the fuse ends during testing. Other fuse types often have different form factors or enclosed bodies, making direct end contact less practical for standard contact-point testing.
