Name the device which is being used increasingly in place of fuse.

Answer

**Step-by-Step Solution:**

1. **Understanding the Function of a Fuse**: A fuse is a safety device used in electrical circuits to prevent excessive current flow, which can lead to overheating and potential fires. It consists of a metal wire that melts when the current exceeds a certain level, breaking the circuit.

2. **Identifying Alternatives to Fuses**: In modern electrical systems, there are devices that can replace fuses. These devices serve the same purpose of protecting circuits from overcurrent but have additional features.

3. **Introducing the Miniature Circuit Breaker (MCB)**: One such device that is increasingly being used in place of traditional fuses is the Miniature Circuit Breaker (MCB). Unlike fuses, MCBs can be reset after they trip, which makes them more convenient for users.

4. **How MCBs Work**: MCBs operate automatically. When the current flowing through the circuit exceeds a predetermined limit, the MCB trips, cutting off the electrical supply. This prevents damage to the circuit and reduces the risk of fire.

5. **Conclusion**: Therefore, the device that is being used increasingly in place of fuses is the Miniature Circuit Breaker (MCB).
