That puts it on pumps, fans, conveyors, and small compressors where 5 HP of variable-speed control is the load envelope — sized to the motor, not above it, so the drive's continuous current and the motor's full-load amps line up at the same point on the torque curve. ## Input current, output range, and torque headroom The drive draws 14 A on the 460 V 3-phase input, with a maximum output frequency of 0.00–600.00 Hz under normal duty and 0.00–300.00 Hz under heavy duty — the wider normal-duty band is what makes the C200 usable for high-speed spindle or pseudo-servo applications, not just fans. A 200% torque-current limit gives the C200 the starting punch needed for conveyors and mixers where the breakaway load is well above the running load — the headroom is what lets the drive hold the motor through the first second without stalling. V/F, SVC, V/F+PG, and FOC+PG control modes are all available, so the same drive runs in plain volts-per-hertz for a simple fan, in sensorless vector for torque-sensitive loads, or in closed-loop vector with an encoder for the most demanding speed-holding applications. ## Where the C200 sits in the Delta line Inside the C200 family, the 3.7 kW VFD037CB43A-20 sits between the 230 V-class VFD037CB23A-20 — same power, different input voltage — and the 460 V VFD040CB43A-20 / VFD055CB43A-20 frames at 4.0 kW and 5.5 kW, which step input current from 14 A up to 15.5 A and 17 A respectively while keeping the same chassis, IP20 rating, and output envelope.","metaTitle":"Delta VFD037CB43A-20 C200 VFD, 3.7 kW, 460 V 3-phase","metaDescription":"Delta VFD037CB43A-20 C200-series economy vector drive, 3.7 kW / 5 HP at 460 V 3-phase, IP20 wall-mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"title":"VFD037CB43A-20","Weight":"1.5 Kg","Version":"A=Wall mount","C200 Series":"CB","Product No.":"VFD037CB43A-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":"14","Input Voltage":"43: 460 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":"037:5 HP(3.7 kW)","Max.

The chassis and footprint match, but the input voltage class is different and is encoded in the order code for that reason.
