3.13 Fuse Selection for Type 2 Coordination
Type 2 coordination is achieved by using semiconductor fuses. These fuses must be able
to carry motor start current and have a total clearing I
2
t less than the I
2
t of the soft starter
SCRs.
When selecting semiconductor fuses for soft starter, use the I
2
t values in the table.
For further information on selecting semiconductor fuses, contact your local distributor.
