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.
