10.3.7 Branch Component Layout (Standard Circuit)
Fuse assignment
The utilization class according to which the motor branch with soft starter is
dimensioned depends on the requirements of the application. Normally, a fuseless
design (combination of circuit breaker + soft starter) is sufficient. If the requirements
for utilization class 2 must be met, semiconductor fuses must be used in the motor
branch.
1) The rated motor current must be taken into consideration during device selection.
2) For utilization class, see page 10-20.
