It carries the standard C200 control set — V/F, sensorless vector (SVC), V/F with PG feedback, and FOC with PG feedback — so the same drive covers fan/pump V/F work on one end and a closed-loop vector spindle or winder on the other without changing the panel footprint. ## Ratings and what they mean for fit The 7.2 A input current and 200% torque-current limit define the overload ceiling this drive will deliver into a motor: 200% torque current is the transient capability for accel/decel ramps, not the continuous rating — duty cycle and motor thermal limit matter more than the peak number for sizing. Output frequency tops out at 600 Hz in normal duty and 300 Hz in heavy duty, which means a 0.5 HP motor on a high-speed spindle or a small blower running past 200 Hz is in normal-duty territory, while constant-torque conveyors and mixers stay inside the heavy-duty map. ## Sourcing posture and lifecycle read No official second-source or successor is recorded for this specific code. The same C200 platform covers higher-horsepower slots in the family — 3.7 kW / 5 HP on the 230 V 3-phase rail and 4.0 kW / 5.5 HP plus 5.5 kW / 7.5 HP on the 460 V 3-phase rail — but those are different ratings, different input currents (20 A, 15.5 A, 17 A respectively), and not direct drop-ins for a 0.4 kW panel position.","metaTitle":"Delta VFD004CB21A-20 VFD, 0.4 kW, 230 V 3-phase","metaDescription":"Delta VFD004CB21A-20 economy vector C200 drive, 0.4 kW / 0.5 HP at 230 V 3-phase, IP20 wall-mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 240V"],"specifications":{"title":"VFD004CB21A-20","Weight":"1.5 Kg","Version":"A=Wall mount","C200 Series":"CB","Product No.":"VFD004CB21A-20","Series Name":"VFD = Variable Frequency Drive","description":"Economy Vector Control Drive C200 Series","Product type":"Economy Vector Control Drive C200 Series","IP Protection":"20: IP20/UL Open Type","Input Current":"7.2","Input Voltage":"23: 230 V 3-PHASE","Control Method":"1: V/F, 2: SVC, 3: VF+PG, 4: FOC+PG","Shipping Weight":"3 Kg","lifecycle_stage":"current","Torque Limit Max.":"200% torque current","Estimated Lead Time":"Usually ships in 1-10 working days.","Applicable motor capacity":"004:0.5 HP(0.4 kW)","Max.
