Schneider ATV650D11N4 Altivar Process ATV650 IP55 Variable Speed Drive

Product Overview

The Schneider ATV650D11N4 is an 11 kW, 15 HP Normal Duty variable speed drive from the Altivar Process ATV650 range. It is designed for three-phase 380–480 VAC systems and uses an IP55 wall-mounted enclosure.

The drive is intended for process applications such as pumps, fans, compressors, HVAC systems, water treatment and plant utilities. Embedded Ethernet, process PID control, multi-pump management, energy monitoring and diagnostic functions support both local operation and integration with industrial automation systems.

The 11 kW rating applies to Normal Duty selection. Heavy Duty motor power and output current must be verified against the motor nameplate and load profile.

Compatible System and Applications

The ATV650D11N4 is suitable for industrial pumps, process fans, compressors, HVAC equipment, cooling systems, water-treatment installations and plant utility machinery.

It is particularly relevant where an IP55 wall-mounted process drive is required without installing a standard open drive inside a separate control cabinet.

Final sizing must consider motor rated current, Heavy Duty requirements, load inertia, process demand, switching frequency, environmental conditions and network integration.

Maintenance and Replacement Notes

Verify the full ATV650D11N4 model, motor current, enclosure type and voltage class before replacement.

Record process settings, PID configuration, motor parameters, Ethernet addresses, I/O mapping, firmware, display settings and installed option modules.

Check the cooling system, IP55 enclosure seals, gland plate, power terminals, control terminals, display and communication ports when assessing a used drive.

Related Models

Adjacent ATV650 N4 models include ATV650U75N4 at 7.5 kW and ATV650D15N4 at 15 kW.

ATV630D11N4 has a different enclosure arrangement and should not automatically replace ATV650D11N4 in an exposed wall-mounted installation.

Inquiry and Supply Notes

Please provide the complete original reference, motor nameplate, supply voltage, motor current, process application, installation environment and required communication protocol.

Heavy Duty rating, output current, gland-plate configuration, firmware, product condition, testing, packaging, availability and delivery time must be confirmed before quotation.
