Motor feeders with soft starters
The type of coordination according to which the motor feeder
with soft starter is mounted depends on the application-specific
requirements. Normally, fuseless mounting (combination of
motor starter protector and soft starter) is sufficient.
If type of coordination "2" is to be fulfilled, then semiconductor
fuses must be fitted in the motor feeder.
1)
The rated motor current must be considered when selecting the devices.
Type of coordination 1 according to IEC 60947-4-1:
After a short-circuit incident, the unit is defective and
therefore unsuitable for further use (protection of
persons and system guaranteed).
Type of coordination 2 in according to
IEC 60947-4-1: After a short-circuit incident the unit
is suitable for further use (protection of persons and
system guaranteed).
The type of coordination refers to soft starters in
combination with the stipulated protective device
(motor starter protector/fuse), not to any additional
components in the feeder.
The types of coordination are indicated in the
corresponding tables by the symbols shown on
orange backgrounds.
