Types of coordination

Types of coordination
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 needs to be
fulfilled, semiconductor fuses must be fitted in the motor feeder.
