Output current is rated 110 A normal / 105 A heavy, with input current 114 A normal / 108 A heavy, so the upstream feeder and breaker have to carry the heavy-side figure and the disconnect sized above the inrush profile. ## Normal vs heavy duty — pick the right rating for the load Delta publishes two parallel ratings on this chassis: 55 kW / 110 A on Normal duty and 45 kW / 105 A on Heavy duty. The Normal figure assumes variable torque loads like fans, pumps, and centrifugal compressors where overload is brief; Heavy is constant torque — conveyors, mixers, extruders, hoists — where the drive has to deliver rated current continuously and survive higher transient torque. Output capacity runs 88 kVA normal / 84 kVA heavy, and input current tracks at 114 A / 108 A. Efficiency is listed at 97.8 %, which is the conduction-loss floor for this output class — the remaining watts land in the heatsink and need cabinet airflow clearance per the C2000 installation guide. ## Sourcing posture Mount pattern, depth, and cable-bend clearances all scale with frame.","metaTitle":"Delta VFD550C43A C2000 Drive, 55 kW, 400V class","metaDescription":"Delta VFD550C43A C2000 series AC drive, 55 kW normal / 45 kW heavy, 380-480V input, Frame D.
