NFD01.1-440-025

The Bosch Rexroth Indramat NFD01.1-440-025 from the NFD Mains Filters series is a robust three-phase mains filter designed to safeguard industrial power lines. With a Nominal Voltage range of AC 115 to 440 V and a Rated Current of 25 A, this unit provides versatile integration across a wide variety of control cabinets and power systems. Its primary function is to reduce line distortion and suppress interrupting radio-frequency signals, ensuring stable power delivery to sensitive drive converters and servo systems.

Featuring a rugged compact design, the NFD01.1-440-025 employs natural convection cooling to maintain optimal operating temperatures without the need for additional fans. It is configured for direct connection to a three-phase AC 440 V, 50/60 Hz supply, consuming 25 A during continuous operation. The filter is rated for altitudes up to 1,000 meters above sea level and is specified to operate reliably within an ambient temperature range of 0 to +40 °C and relative humidity up to 90%. This product delivers full EMC compliance, meeting stringent industrial standards for electromagnetic interference suppression.

Designed for seamless compatibility, this mains filter installs easily in standard control cabinets alongside frequency converters and transformers. A minimum ventilation gap must be maintained when multiple units are mounted together to ensure efficient heat dissipation. The durable construction and natural convection cooling eliminate moving parts, reducing maintenance requirements and enhancing long-term reliability. By mitigating power-line disturbances and ensuring compliance with EMC regulations, the NFD01.1-440-025 contributes to increased uptime and operational efficiency in demanding industrial environments.
