Product Description:

The FECP01.1-55K0-3P400-A-BN-NNNN-01V01 is a frequency converter produced by Bosch Rexroth Indramat for the FEC Frequency Converters series. It is intended for variable-speed operation of centrifugal pumps and axial fans in automated plants, where accurate torque regulation lowers energy use and mechanical stress. By modulating the output voltage and frequency delivered to the motor, the converter matches pump or fan speed to real-time demand and supports coordinated control through PLC interfaces.

This model delivers a rated output of 55 kW, giving it enough reserve for mid-range process drives. It belongs to the 400 VAC voltage class and accepts a supply window of 3 AC 380 to 480 V, allowing installation on standard industrial mains without an autotransformer. Two overload profiles are integrated: up to 120% for 60 seconds for rapid acceleration and 105% for 60 minutes for extended load peaks, both monitored by the internal thermal model. Input power is fed through three phases, and an external brake chopper can be connected to dissipate regenerative energy during fast deceleration. Mechanical size 5 and a large front panel provide ample space for terminations and I/O, while the housing omits a potentiometer so all adjustments are made digitally. The unit is built for high durability in continuous-duty plant operation.

The converter carries an IP20 protection class, so it must be installed in a closed cabinet but remains accessible for tool-free wiring once de-energized. Cabinet layout is simplified by the unit’s 364 mm width, and the symmetrical busbar pattern matches the 3-phase topology of upstream breakers and contactors. As a 1st generation unit built to Design 1 guidelines, it uses the early FEC platform layout while still meeting present-day efficiency targets.
