Product Description:
The HNF01.1C-F240-E0055-A-480-NNNN is a mains filter from Bosch Rexroth Indramat in the HNF Mains Filters series. The unit is installed on the incoming power side of industrial automation equipment to condition the three-phase supply before it reaches servo drives and related motion hardware. Placed ahead of the drive system, it helps reduce conducted interference between the supply network and the power electronics inside the cabinet. This role supports stable operation in multi-axis production cells that depend on a controlled line supply.
The filter accepts a three-phase input of 400–480 V AC, allowing it to match standard industrial low-voltage networks without additional autotransformers. Operation on both 50/60 Hz systems means the same hardware can be used in regions with different mains frequencies. The housing carries an IP20 degree of protection, so live parts are finger-safe and the device is intended for installation inside a closed control cabinet. Because the unit is specified for feeding devices only, it is used upstream of drive controllers rather than connected directly to actuators. That arrangement keeps line conditioning at the cabinet entry point, where the filter can serve the complete drive section through a common supply path. Within the internal product coding, it is classified under series 01, which identifies this generation of HNF filters.
The mechanical build follows design version 1, which indicates the first released construction style and the associated mounting and connection layout. Electromagnetic behavior is rated as C2 according to DIN EN 61800-3, making it suitable for industrial installations with controlled supply conditions. The filter is intended for cabinet-based drive group installations where several power stages share one incoming mains connection. Application coverage extends to systems that coordinate 6 axes, so one filter can support a complete multi-drive rack. To limit capacitive charging current on long motor leads, the total cable run between the drives and motors is restricted to 240 m when this filter is used.
