The Schneider Electric VW3A68553 is a motor output choke rated for 580 A continuous at 400/500 V AC. It sits between the drive output and the motor cable in an Altivar VFD installation, limiting the rate of voltage rise (dV/dt) and reducing reflected-wave peaks on long cable runs. For a 580 A frame, this choke is sized for a large drive — think multi-motor conveyors, high-power pumps, or a single large induction motor on a 400/500 V three-phase supply.
Sourcing reality — lifecycle and availability
The VW3A68553 carries an Obsolete product status from Schneider Electric.
What the 580 A rating means for fit
The 580 A rating at 400/500 V defines the continuous current the choke can carry without saturating or exceeding its thermal limit. In a drive system, the choke must be sized for the motor's full-load current, not the drive's rated output — a 580 A choke typically pairs with a drive rated around 315 kW to 400 kW on 400 V, depending on the motor's duty cycle and cable length. The 400/500 V voltage range covers standard low-voltage industrial three-phase networks (400 V in Europe, 480 V in North America, 500 V in some mining and marine applications).
Deployment context
This choke is a panel-mounted component, typically bolted to the backplate near the drive output terminals. It adds inductance to the motor circuit, so cable routing should keep the choke output wires separate from control and feedback cables to avoid coupling noise into encoder or sensor signals. For IP-rated enclosures, the choke's own thermal dissipation (several hundred watts at full load) must be factored into the panel cooling calculation.
