What the 24-pulse input buys you on harmonics
The ATV1200A4704242: The 24-pulse diode rectifier bridge (cite:) cancels the 5th, 7th, 11th, and 13th harmonics at the input — you stay below IEEE 519 distortion limits without an external filter. The integrated EMC filter (cite:) handles the conducted emissions side. For a site with a weak grid or multiple drives on the same transformer, this saves the cost of a separate harmonic trap cabinet. Apparent power is 470 kVA (cite:), line current 65 A (cite:). The prospective short-circuit current rating is 31.5 kA for 150 ms (cite:) — the drive's input stage can ride through a fault on the primary side without the upstream breaker clearing first. Dielectric strength between earth and power terminals is 20 kV AC (cite:), which covers the transient overvoltages expected on a medium-voltage bus. Overload capability is specified in two duty bands: 1.2× rated current for 60 s (standard overload) or 1.5× for 3 s; the high-overload profile gives 1.5× for 60 s and 1.85× for 3 s (cite:). That second band matters if the driven load — a crusher, centrifuge, or conveyor with a high breakaway torque — needs extra current during acceleration.
Floor-standing enclosure — what fits through the door
The drive ships in a floor-standing enclosure with separate air flows for the power section and the control electronics (cite:). Standard-efficiency configuration: 1400 mm deep, 2660 mm wide, 2520 mm high (cite:,). High-efficiency option adds 100 mm to depth, 300 mm to width, and 150 mm to height. Cooling airflow is 9900 m³/h standard, 13200 m³/h high-efficiency (cite:) — plan the room ventilation around that exhaust volume. Operating altitude range is 1000-2000 m with a 0.6% current derating per 100 m above 1000 m (cite:). The 80 dB noise level (cite:) means ear protection in the drive room is mandatory — not a surprise for an MV drive, but worth flagging for the site acoustics plan.
