Thermal Unit Selection General - Steven Engineering

c For Class 8630 starters divide the delta connected motor full load current by 1.73, and use this quotient to select thermal units. d For Class 8640 and Class 8940 (MD, PD, ME, PE, MF, PF, MG and PG) starters use the full load cu rrent of each motor winding as a basis for thermal unit select ion—normally one-half total motor current. ................
