Short answer: fuse cutout models should be selected by rated voltage, rated current, breaking capacity, creepage distance, insulator material, fuse link type and mounting method.
| 11kV or 15kV cutout | Used for medium-voltage distribution protection. Confirm system voltage and insulation level. |
|---|---|
| 24kV or 27kV cutout | Used for higher distribution voltage networks. Confirm creepage distance and pollution level. |
| 36kV cutout | Used where system voltage and utility standard require higher insulation rating. |
| Polymer or porcelain | Housing material should match project standard, mechanical load and pollution environment. |
Fuse cutouts should not be quoted from voltage alone. Breaking capacity, creepage distance and fuse link rating must also match.
