ATV630D18N4 Variable Frequency Drive Altivar 630 18.5kW 3-ф/380

ATV630D18N4: Schneider Electric Altivar 630 variable frequency drive rated at 18.5 kW (3-phase 380 V input, 3-phase 380 V output). We use it for an industrial pump, fan, or compressor package when the project needs Altivar diagnostics and a predictable automation path.

• Parameters: 39,2 A output current, IP21, 110-130% overload, maximum frequency 500 Hz.
• What matters: This is the pump/fan side of Altivar Process; IP20/IP21 is best mounted in a ventilated cabinet.
• Check before use: Before commissioning, check motor current, load type, cable length, and the control method.

Schneider Electric Altivar 630: where this series fits

Altivar 630 is an Altivar Process ATV600 in wall-mounted IP21 format for pump and fan processes. Our catalog currently has 16 active items in this series: 0.7-75 kW, supply variants 3-phase 380 V, IP21 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 630

• Common mechanisms: pump stations, HVAC, compressors, process fans, and SCADA integration.
• 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 630 is not the right drive

We do not recommend Altivar 630 for open dusty or wet mounting without a cabinet, where ATV650 is the better format. 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.
