Product Description:

The FC202P75KT4E20H2XGXXXXSXXXXAXB is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. The unit is intended for pump and fan duties in water and wastewater installations, where it modulates induction motor speed to maintain stable flow or pressure under varying process demands. Through frequency conversion and embedded monitoring functions, it supports continuous-duty automation while lowering energy consumption and mechanical wear across the driven equipment.

At a rated power of 75 kW, the drive can maintain large centrifugal pumps within their optimal efficiency range. When supplied from 380–440 V mains, it delivers a continuous output current of 147 A, and this capacity adjusts to 130 A on 441–480 V networks, allowing cables and protective devices to be sized correctly for regional voltages. Overall conversion efficiency reaches 0.98, so only a small fraction of the input energy is lost as heat, simplifying panel ventilation. The open-chassis construction carries an IP20 enclosure rating, indicating that the terminals must be mounted inside a cabinet to prevent contact and exposure to debris.

The protection chain begins with a maximum pre-fuse rating of 250 A, which limits fault current before it reaches the inverter bus. The output terminals have a peak phase-to-phase voltage of 1.030 kV through a 5 m cable at a nominal voltage of 400 V; this limit is used when checking motor insulation requirements. Under the same conditions, the waveform rises within 0.364 µs and exhibits a dv/dt of 2.264 kV/µs, allowing winding stress and the need for output filters to be evaluated. Because the drive is supplied without an internal brake chopper, an external brake resistor can use conductors up to 95 mm², while power feeders may reach 150 mm² (300 MCM) through the standard cable entries.
