ATV340D18N4E Variable Frequency Drive Altivar 340 18.5 kW 3x380

ATV340D18N4E: Schneider Electric Altivar 340 variable frequency drive rated at 18.5 kW (3-phase 380 V input, 3-phase 380 V output). We use it for a dynamic conveyor, extruder, or machine with sharp load changes when the project needs Altivar diagnostics and a predictable automation path.

• Parameters: 46 A output current, IP20, 150% overload, maximum frequency 600 Hz.
• What matters: ATV340 is selected for dynamics and automation: Ethernet, CANopen, and encoder options are useful on machine modules.
• Check before use: Before commissioning, check motor current, load type, cable length, and the control method.

Schneider Electric Altivar 340: where this series fits

Altivar 340 is a high-performance machine-drive series for dynamic drives and automation integration. Our catalog currently has 19 active items in this series: 0.7-55 kW, supply variants 3-phase 380 V, IP20 enclosures, EMC filter: yes. Schneider Electric is not the cheapest route. The usual reason is simpler: Altivar diagnostics, SoMove, documentation, and a predictable cabinet startup.

Typical jobs for Altivar 340

• Common mechanisms: packaging lines, positioning axes, material-handling mechanisms, and fast machines.
• Selection: first check motor current, load duty, supply voltage, IP rating, and motor cable length.
• Commissioning: with Altivar, define the command source, speed reference, network protocol, and braking need before wiring.

When Altivar 340 is not the right drive

We do not recommend Altivar 340 for a simple fan or pump where ATV212 or ATV630 is enough. In those jobs, another Schneider Electric series may be more logical, or INVT / Veichi may be enough when the project does not specifically require Altivar.

Our field note

Schneider Electric is usually chosen for sites with BMS, SCADA, or an older Altivar already in the cabinet. Predictability matters there. Before ordering we ask for a motor nameplate photo and a short mechanism description. That filters out 220/380 V, IP, and braking mistakes early.
