current

Note:1 .The aboveid rated parameters for single pipe , the fuses can be parallel connected by fixed structure to geta high rated current.
2.Sizes in the bracket are for inserting fuses.

Installation Dimensios

Main technical characteristics

1.In required working conditions, the fuse can break any fault current between the minimum break current 1.6-3 and the rated 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 for I²t property.
