HNF01.1A-A075-E0309-A-500-NNNN

The Bosch Rexroth Indramat HNF01.1A-A075-E0309-A-500-NNNN from the HNF Mains Filters series by Bosch Rexroth Indramat features a nominal current of 309 A and a mains connecting voltage of AC 400–500 V. Rated for an EMC industrial area per DIN EN, this three-phase filter supports a maximum input voltage of 3 × 480 VAC and is designed with a line code 1 and variant code 1 for precise identification. The device is compatible with one-axis systems and permits a maximum cable length of 75 m to accommodate flexible cabinet layouts. It utilizes a Feeding Units only supply system to ensure stable power distribution in demanding environments.

The filter incorporates an E type supply system and may be used exclusively with feedback devices, preventing improper connections to pumps or blowers. It effectively suppresses interference for three-phase drive controllers up to 480 V and complies with DIN EN 61800-3 EMC limits. Housed in an IP20 enclosure, the unit must be mounted inside a control cabinet in the standard position to maintain protection and performance. An isolating transformer is recommended between the mains and filter when using grounded outer conductors, ensuring safe separation of supply circuits.

This mains filter is specifically engineered for integration with Rexroth HCS and HMV converters, optimizing drive performance and EMC compliance. Commissioning should follow converter programming to enable accurate monitoring and control of the manufacturer’s motors. As part of Bosch Rexroth Indramat’s extensive electrical product portfolio, the HNF01.1A-A075-E0309-A-500-NNNN exemplifies rigorous quality standards and global logistical support for international deployment.
