ATV320U55N4C
Schneider Electric
Overview
The ATV320U55N4C is a Variable speed drive in the Altivar Machine ATV320 range from Schneider Electric. It is engineered for industrial automation duties within the Altivar variable speed drive ecosystem.
Application & Technical Notes
As a variable speed drive, the ATV320U55N4C is intended for deployment in panel-based control cabinets and machine enclosures where Altivar variable speed drive equipment is installed. It regulates the speed, torque and position of an AC motor to match the process demand while protecting the mechanical train.
Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.
Maintenance & Diagnostics
Maintain clearances for cooling, back up the motor parameter file, and verify the thermal setting matches the driven load. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the ATV320U55N4C, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the drive rating, supply voltage and motor parameters, and confirm the option cards and communication profile required by the application. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
