Product Description:

The 131B6085 variable frequency drive is produced by Danfoss under the VLT FC 301 Automation Drives series. Within the VLT AutomationDrive FC product group, it carries the internal series identifier 301. The unit is intended for speed control of three-phase induction motors in automated conveyor, pump, and fan stations, allowing plant controllers to match motor torque and speed to process demand. Its mechanical outline supports dry-room installation in switchgear that accommodates B, C, D, and E frame cabinets. This arrangement keeps the drive protected while allowing access to its power, motor, and control connections.

The drive has a rated output of 30 kW, which corresponds to 40 HP at the motor terminals. The input section accepts 380–480 VAC from industrial power supplies and is configured for three-phase power. Enclosure protection meets IP21 / Type 1, guarding the electronics against solid objects larger than 12 mm and vertically dripping water. The drive does not include a brake chopper, so external dynamic braking hardware must be used when the application requires controlled dissipation of regenerated energy. It also does not include a dedicated mains option. The baseline configuration is suitable for systems that provide any required line-side accessories separately.

Lateral wiring is routed through standard cable entries, simplifying gland plate selection while preserving enclosure integrity. A graphical local control panel provides direct access to operating values, settings, and drive parameters from the cabinet door. The integrated radio-frequency interference stage is classified as RFI Class A1/B, providing line-side electromagnetic interference suppression for compatible industrial installations. The drive uses coated printed circuit boards to improve resistance to airborne moisture and dust commonly found in production areas. The coating helps protect sensitive electronic components when the unit is installed in dry indoor cabinets. Adequate cabinet ventilation and the required installation clearances should be maintained to support normal heat dissipation during continuous operation.
