The ABB 3ADT218587S0141 is a DCS880-S01-2000-04 DC converter — a 2-quadrant unit rated for 2000 A on a 400 VAC supply. It sits in frame size H6, which governs the mechanical footprint and bus-bar layout for the cabinet build.
The 2000 A rating is the continuous output at the stated line voltage — size your DC bus and fusing for that full current, not less. The 2Q topology means it handles motoring and regenerative braking in one direction only; if your application needs bidirectional torque or overhauling loads, you will need a 4Q variant. Frame H6 is a physical size class — expect a substantial cabinet footprint and bus-bar connections rated for the full current. The 73 dB(A) sound level is typical for a converter of this power class; plan for hearing protection if the drive is in a manned area. The analog complement — 3 inputs, 2 outputs — is enough for speed reference, torque limit, and a speed-feedback or load-signal output. No fieldbus interface is listed here, so plan on using the analog I/O or adding a communication option card if needed.
Environmental and installation notes
The converter is rated for 5 to 95 % relative humidity (non-condensing) and a 50 Hz supply. Auxiliary terminals carry an IP00 protection level per IEC 60529 and IEC 60947-1 — meaning they are not touch-safe; the cabinet door must interlock or require a tool to open.
