Product Description:
The FC-301P37KT2131F0579 is an AC variable frequency drive from Danfoss within the VLT FC 301 Automation Drives series. The unit converts fixed-frequency three-phase mains power into a controlled output for regulating the speed of induction motors in conveyors, pumps, and other industrial equipment. Closed-loop torque and speed control supports accurate process operation and can reduce energy consumption when motor output is adjusted to match the load.
In heavy-overload mode, the drive can deliver a continuous output current of 143 A. Normal-duty operation permits a continuous current of 170 A and a short-term current of 187 A, while the input section draws a maximum of 130 A at rated load. The drive accepts 200–240 VAC three-phase power and provides 37 kW of shaft power. Its continuous apparent power is 51.5 kVA, providing the electrical capacity required for motor operation and acceleration. The C2 frame measures 370 mm wide, 332 mm deep, and 780 mm high. Its stainless steel enclosure has an IP66 / NEMA 4X rating, protecting internal components from dust, water jets, and common washdown conditions in industrial facilities.
Power loss reaches 1,400 W during heavy-overload operation and 1,636 W during normal-duty operation, which should be considered when planning ventilation and heat removal. The housing is 780 mm tall and has a mass of 55.59 kg, so the mounting surface must support the drive securely during operation and service access. Conducted emissions comply with EN 55011 Class A2 requirements for industrial electrical environments. The 370 mm width and 332 mm depth provide the footprint needed when arranging the drive with other equipment inside or alongside a control enclosure. Adequate clearance around the housing helps maintain airflow and provides access to power, motor, and control connections without obstructing adjacent components.
