ATV950D11N4E Variable Frequency Drive Altivar 950 11.0kW 3-ф/380

ATV950D11N4E: Schneider Electric Altivar 950 variable frequency drive rated at 11 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: 23,5 A output current, IP55, 110-130% overload, maximum frequency 500 Hz.
• What matters: This is the ATV900 line for heavier mechanics: high torque, braking, encoder options, and network options.
• Check before use: IP55 does not remove the need for cooling: do not block the heatsink or mount the drive in a hot pocket.

Schneider Electric Altivar 950: where this series fits

Altivar 950 is an IP55 Altivar Process ATV900 version for heavy mechanisms in harsher environments. Our catalog currently has 28 active items in this series: 0.7-75 kW, supply variants 3-phase 380 V, IP55 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 950

• Common mechanisms: conveyors, cranes, mills, and drives that are better mounted closer to the machine.
• 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 950 is not the right drive

We do not recommend Altivar 950 for a clean electrical room or a job without heavy torque where ATV930 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.
