hi folks!
Enclosed herewith Siemens Type-2 co-ordination table for Fuseless & fuse protected selection for IE-2 motor.
why contactor ratings are different when used with breakers & fuses.
e.g. For 75 kW 415V IE2 Motor
Fuse less : Line & Delta contactor ratings : 150 A & Star: 65A
Fuse protected : Line & Delta contactor ratings : 80 A & Star: 65A
can anybody elaborate on this.
regards,
