What AFIN-01C actually is
The ABB AFIN-01C sits on the fan inverter 1 kW line as an installation accessory — the medium description and title both read FAN INVERTER 1 KW, with the product name field tagged 'Installation accessories noble' and the part-type entry marked New. In practice that puts it on the BOM alongside a 1 kW-class ABB drive or fan-inverter package, not as the inverter itself.
Form factor and handling
The on-record technical information gives a 100 x 140 footprint, which is the only dimensional handle the spec sheet offers; the shipping weight reads 1.2 Kg, light enough for a single-handed install into a fan-inverter cubicle. No IP or enclosure rating is published on this listing, so treat it as an indoor panel-build item unless the project spec says otherwise.
