The maximum fuse size given:
1. Means that the conditional short-circuit current of the switch disconnector fuse is 50KA.
2. Ensures a minimum of TYPE 1 co-ordination for contactors to EN 60947-4-1: 1992 with a conditional short-circuit current of 50KA.
3. Ensures that the ultimate allowable short-time conductor temperature under short-circuit conditions is not exceeded
in accordance with EN 60204-1: 1992.
Fuses not exceeding the 5 seconds interruption current given in the table Switch Disconnector/Fuse
