NFD04.1-440-025

NFD04.1-440-025, Bosch Rexroth Indramat, NFD Mains Filters is a high-performance mains filter engineered for industrial drive controllers and power supply systems. It conditions input power by filtering out high-frequency noise generated during servo motor deceleration, preventing it from reaching upstream circuits and degrading system performance. Built for heavy-duty use, this unit integrates clear safety signage on its enclosure to alert operators to potential hazards during installation and maintenance. Its compact design fits neatly into control cabinets, minimizing footprint without compromising on filtering capacity.

The filter’s technical credentials are robust: it supports a Nominal Voltage range of AC 115 to 440 V, handles a continuous Rated Current of 25 A, and belongs to Line 04 within the NFD series. Heat dissipation is managed via natural convection, eliminating the need for fans and reducing maintenance points. An IP56 protection class enclosure shields internal components from dust and water ingress, ensuring reliable operation in harsh industrial environments. Built-in leakage current suppression safeguards against stray capacitance currents while maintaining compliance with EMC regulations. Additionally, integrated safety signage and symbols facilitate code-compliant installation, and the unit’s one-year warranty underscores Bosch Rexroth Indramat’s commitment to quality.

Engineers will appreciate how easily the NFD04.1-440-025 interfaces with servo drive modules, enhancing system reliability by mitigating EMI and prolonging upstream component lifespans. Its maintenance-free cooling and rugged protection class minimize downtime and service intervals, delivering consistent performance in applications ranging from metal forming and printing to food processing and paper converting. With its proven filtering capability and industrial-grade construction, the NFD mains filter is an indispensable asset for any advanced automation or drive control setup.
