Product Description:

The FC-301PK55T4E20 is a compact AC variable frequency drive produced by Danfoss and assigned to the VLT FC 301 Automation Drives series. The unit modulates the speed of standard induction motors by converting constant-frequency plant power into a controlled output waveform, allowing conveyors, pumps, and small process equipment to match load demands without mechanical throttling. Within an automation cell, it functions as the final power stage, executing speed commands from a PLC while providing status feedback and basic motor protection. This method of control allows smoother acceleration and deceleration than direct line starting, which can help stabilize process flow in light-duty machine sections.

The drive’s electrical rating is 0.55 kW, which corresponds to 0.75 HP. An input range of 380 – 480 VAC allows direct connection to common industrial feeders used in 400 V systems, so a separate voltage-conversion stage is usually unnecessary. The drive operates on three-phase power, which helps keep current balanced across the supply conductors during normal operation. The enclosure is classified as IP20 / chassis, so it is finger-safe but intended for installation inside a cabinet or machine enclosure rather than in an exposed location. The unit uses normal cabinet mounting in A, B, and C frames, which follows the standard installation format used across comparable FC-series drive sizes.

The product belongs to the VLT AutomationDrive FC line, which groups it with automation-focused drives built on the same control platform. The designation 301 identifies the FC 301 variant within that line. That platform keeps the parameter structure and user interface format consistent across comparable units. As a result, mixed-drive panels can retain a familiar control layout even when motor sizes differ from one axis or process section to another.
