HRC Fuse Links |
The letter indication according to fuse standard
The first letter shall indicate the breaking range: |
| g = fuse-links (full-range breaking-capacity fuse-links |
|
| a = fuse-links (partial-range breaking-capacity fuse-links |
|
The second letter shall indicate the utilization category; this
letter defines with accuracy the time-current characteristics,
conventional time and currents, gates: |
| gG = indicates fuse-links with a full-range breaking capacity for general application |
|
| aM = indicates fuse-links with a partial range breaking capacity for the protection of motor circuits |
|
NOTE 1 - At present gG fuse-links are often used for the protection of motor circuits, which is possible when their characteristics are suitable to be capable of withstanding the motor starting current. |
