FC-103N355T4E20H4XGCXXXSXXXXAXBKCXXXXD0 by Danfoss

The Danfoss FC-103N355T4E20H4XGCXXXSXXXXAXBKCXXXXD0 from the VLT FC 103 Refrigeration Drives series by Danfoss is a heavy-duty Frequency Inverter Drive designed for precise control in industrial refrigeration applications. Housed in an IP20 enclosure, this chassis-style drive accommodates a three-phase input voltage range of 380–480 V AC and operates at 50/60 Hz. With an input current of 634 A @ 50 Hz or 569 A @ 60 Hz, the unit delivers stable power conversion under varying load conditions, ensuring smooth start-up and consistent compressor speed control.

Measuring 1578 mm in height, 507 mm in width, and 482 mm in depth, the FC-103N355T4E20H4XGCXXXSXXXXAXBKCXXXXD0 integrates a robust chassis design that supports deep installation in control panels. The device outputs three-phase power across a frequency range of 0–590 Hz, providing output currents of 658 A @ 50 Hz and 590 A @ 60 Hz. Its enclosure type and rating guarantee protection against accidental contact, while the precise tolerance of the IP20 rating allows for efficient air circulation.

Built for demanding industrial environments, this drive tolerates ambient temperatures up to 40 °C (104 °F) in standard operation and up to 55 °C (131 °F) with current derating, ensuring reliability in warm machinery rooms. The drive’s three-phase architecture and 2 HP rated load capability make it compatible with a wide range of refrigeration compressors and pumps. Its efficient power management reduces energy consumption, while the durable chassis construction supports long maintenance intervals. By maintaining precise frequency and voltage regulation, the Danfoss FC-103N355T4E20H4XGCXXXSXXXXAXBKCXXXXD0 enhances system efficiency, extends equipment life, and lowers operational costs in industrial automation settings.
