Page 8: Sizing Guide
Sizing Guide The DFE is designed for general purpose applications and where a traditional Star / Delta is currently used, or would be considered to be appropriate. Generally the motor will start off load, and the time to accelerate to full speed will be in the region of a few seconds. The standard DFE range is suitable for the majority of cases, and conforms to Trip Class5, which means it is capable of withstanding 3 times Full Load Current for 5 second starts. - Page 9 3.5-12: 1188 3-23: 1177 4-19: 1181 4-29: 1171 400V 400V 460V (Standard) (3/Hr) (3/Hr) (3/Hr) (3/Hr) DFE-32 DFE-26 DFE-26 DFE-30 DFE-22 132 A 75 KW 110 HP DFE-34 DFE-30 DFE-30 DFE-32 DFE-24 160 A 90KW 130 HP DFE-36 DFE-30 DFE-32...
