Product Description:

The HNF01.1A-F240-E0202-A-480-NNNN is a mains filter produced by Bosch Rexroth Indramat and supplied within the HNF Mains Filters series. It is installed ahead of drive controllers to attenuate conducted interference on the three-phase supply, helping multi-axis automation cells meet electromagnetic compatibility requirements and maintain reliable motion control. The filter is used on the line side of the system, where it reduces unwanted noise before that energy can spread into the plant network or nearby electronic equipment. Because it works on the incoming mains connection, it helps create a cleaner electrical path for connected drive hardware during normal operation.

This filter is rated for a nominal line current of 202 A, allowing it to support large drive groups without saturation. It accepts input in the range of 3 × AC 400–480 V -15/+10% at 50/60 Hz, so it can be connected directly to common factory distribution networks. The housing carries a protection level of IP20, so it must be mounted in an enclosed panel where contact protection is required. The unit falls under EMC category C3 in accordance with DIN EN 61800-3, which is intended for industrial locations with a dedicated power infrastructure. It is approved for installations that run up to 6 axes with a total motor cable length of 240 m, helping limit voltage spikes and high-frequency noise over that distance.

Additional configuration data identify this device as design version 1 and internal series code 01. These identifiers indicate the specific execution used for this unit within the product line. The supply concept is specified for feeding devices only, which means the filter is intended to precede inverters rather than general-purpose loads. Used in that role, it supports the incoming power path of compatible drive systems instead of motor-side wiring.
