That current figure is what you size the input protection and motor cable for — not the power rating alone. Output frequency spans 0 to 600 Hz, which covers standard 50/60 Hz induction motors and higher-speed spindles without needing a separate drive class. The IP20 enclosure means it lives inside a panel — no washdown or outdoor mounting without a secondary enclosure. ## Active production — sourcing posture We source it through authorized distribution channels against your RFQ. ## Panel integration and ambient limits Three-phase 460 V input means you need a 3-pole breaker or fused disconnect sized for the 11.2 A full-load draw plus a safety margin per NEC 430. The drive's internal DC bus charges through a soft-start circuit, so upstream contactors see limited inrush.","metaTitle":"Delta VFD037E43A AC Drive 480V, 3.7 kW, 11.2 A, IP20","metaDescription":"Delta VFD037E43A AC Drive (VFD) 480V, 3-phase, 3.7 kW, 11.2 A, IP20, 0-600 Hz output.

The VFD037E43A draws 11.2 A versus 7.1 A, so the input protection and cable must be upsized.
