Note:
1.The aboveid rated parameters for single pipe,the fuses can be parallel connected by on-site structure to get a high rated current. 2.Sizes in the bracket are for inserting fuses.
Features
1. In required working conditions,the fuse can break any fault current between the minimum break current 1.6-3 and therated break current.
2. See Chart 3 for time-current property.The section above the minimum break current is by dotted line.
3. See Chart 4 for current limit property.
4. See Chart 5 forl²t property.
