Page 163: Feeder Assembly, Type Of Coordination 2
In order to achieve type of coordination 2, you must provide protection for all thyristors against short circuits by means of special semiconductor fuses (e.g. SITOR fuses from Siemens). A short circuit can occur, for instance, as a result of a defect in the motor windings or in the motor's power supply cable.
