At this rating the drive sits at the top of the FRENIC-Ace lineup, used where a single cabinet powers large pumps, fans, compressors, conveyors, or extruder motors — the IP20/IP00 basic enclosure means the unit is intended for a clean, panel-built enclosure, not a washdown or outdoor cabinet on its own. ## Sizing and panel reality for a 220 kW-class drive A 220 kW / 280 kW rating on three-phase 400V is the headline that decides motor fit — the drive handles any motor within that power band on the 400V mains, with headroom for short overload transients, but the line reactor, harmonic filter, and braking chopper (if retrofitted) must be spec'd against the same maximum current to keep upstream protection tight.","metaTitle":"FRN0520E2S-4C Fuji FRENIC-Ace drive, 220 kW / 280 kW","metaDescription":"Fuji Electric FRENIC-Ace FRN0520E2S-4C AC drive, 220 kW / 280 kW on three-phase 400V, IP20/IP00 enclosure.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drive (VFD) 480V"],"specifications":{"Enclosure":"S = Basic type (IP20/IP00)","Series Name":"FRN = FRENIC series","Manufacturer":"Fuji Electric","Power supply":"4 = Three-phase 400V","Shipping Weight":"131 Kg","lifecycle_stage":"current","Application area":"E = For industrial/High performance/Multiple functionality","Development code":"2 = 2","Weight (kg) [lbs]":"130 [287]","Estimated Lead Time":"1 - 10 Working Days","Amperage rating value":"0520 = 220 kW | 280 kW"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/26be6eb01457283ff290350b1f8f228a.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/FRN0520E2S-4C/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for FRN0520E2S-4C?","answer":"Submit an RFQ against the BOM line for FRN0520E2S-4C and pricing, lead time, and stock vs. quoted-to-order split are confirmed at quote time — the page carries an estimated lead-time window of 1 to 10 working days, but no per-unit price or stock count is published here.
