Dll  Bottle fuse:

 is a type of fuse used primarily in older electrical installations, particularly in residential and light industrial settings. It is named for its distinctive bottle-like shape, with a wide base and a narrowe

r top where the fuse wire is housed. These fuses are often seen in fuse boxes or panels where they protect electrical circuits from overcurrent conditions.

Key Features of a Bottle Fuse:

1. Shape:

The fuse has a cylindrical or conical shape resembling a bottle, which allows it to be easily screwed into a fuse holder.

2.Fuse Element:

 Inside the bottle fuse is a fuse element (usually a wire or strip) that melts when the current exceeds a specified limit, thereby interrupting the flow of electricity.

3. Base:

 The base of the bottle fuse is typically ceramic or similar heat-resistant material, providing insulation and support.

4. Indication:

 Some bottle fuses have a visible indicator, such as a window or color change, that shows when the fuse has blown.

5.Voltage and Current Ratings:

Bottle fuses come in different voltage and current ratings, suitable for various applications.

6. Types:

 They can be found as fast-blow (quick to interrupt the circuit) or slow-blow (allowing brief surges before blowing), similar to glass cartridge fuses.

While bottle fuses are less common in modern installations due to the widespread adoption of circuit breakers and more advanced fuses, they are still found in older homes and certain industrial environments.
