Small fuse

Key Features

• Low Current Protection – Typically rated for currents from 1A to 30A.

• Compact and Lightweight – Fits into small fuse holders and fuse boxes.

• Clear Amperage Marking – Easy to identify the correct rating for replacement.

• Fast-acting or Standard – Available in different response types depending on circuit requirements.

Functions

1. Circuit Protection – Prevents wiring and devices from damage due to overcurrent.

2. Safety – Reduces risk of electrical fires in low-current circuits.

3. Indication of Fault – When a fuse blows, it signals a short circuit or overload in the system.

Common Uses
