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.
