Bosch Rexroth HNF01.1A-F240-R0026-A-480-NNNN Mains Line Filter

Bosch Rexroth HNF01.1A-F240-R0026-A-480-NNNN is a three-phase mains line filter designed for IndraDrive M servo drives, intended for 400–480 V AC supply. As part of the HNF01.1 mains filter family, it is installed on the incoming mains to suppress high-frequency conducted interference and damp transient disturbances that travel along the supply line to the drive. The A-480 designation signals compatibility with nominal three-phase voltages in the 380–480 V range at 50–60 Hz, matching common industrial service feeds. This filter is specifically meant for use with IndraDrive M configurations, helping to minimize noise on the supply and support stable operation in applications such as machine tools, conveyors, robotics, and other automation systems powered from 400–480 V networks. The exact current rating and leakage characteristics for this R0026-A-480-NNNN variant are defined by its sub-suffix within the HNF01.1A-F240 family, so verification against the drive installation manual or Rexroth documentation is recommended to ensure proper pairing with the intended IndraDrive M model and service conditions.
