NFD04.1-440-080

The Bosch Rexroth Indramat NFD04.1-440-080 from the NFD Mains Filters series is engineered to safeguard industrial drive controllers by attenuating regenerative currents generated during motor deceleration. This NFD04.1-440-080 filter features a Line 04 configuration and supports a Nominal Voltage of AC 115 to 440 V, ensuring compatibility with a wide range of three-phase power supplies. Its Rated Current of 80 A enables uninterrupted operation under demanding load cycles, while the compact housing conforms to IP20 protection class standards to guard internal components against solid foreign particles.

Boasting a robust design, the NFD04.1-440-080 integrates seamlessly into servo systems for food processing, textile, and packaging machinery. The filter’s choke windings and internal capacitors suppress voltage spikes and high-frequency noise, reducing electromagnetic interference on the supply network. Its low insertion loss maintains power efficiency, and the minimal leakage current requirement—when properly grounded—ensures operator safety without the need for additional protective measures. Routine maintenance is streamlined by the filter’s modular construction, which allows rapid replacement of subcomponents.

Designed for ambient operating temperatures from 0 to 40 °C, the NFD04.1-440-080 maintains rated performance across typical industrial environments, and can be stored between –25 and +80 °C if not in immediate use. Installed within control cabinets, it operates silently, eliminating audible disruption on the factory floor. Backed by a one-year warranty from the authorized distributor, this mains filter delivers dependable, long-term protection and cost-effective uptime for mission-critical automation systems.
