3-phase Motor with Direct-on-Line Starting

For D.O.L starting at 3phase 1500rpm or 1800rpm squirrel cage motors under AC-3 operating conditions according to IEC609 47-4-1.
Fuse is valid for this motor full load current and for max.
6×f.l.c. starting current and max.5secs starting time.
The setting current of the heater should be adjusted to the motor full-load current.

Notes

This selection scale made up depending upon the average rating current of motor.
Actual rating current could be high or low for a specific motor.
Therefore heater selection on this basis always involves risk.
For fully reliable motor protection, select heaters on the basis of full load current rating as show on the motor nameplate.
Type MSO-N600KP and N800KP are not available.
