Bosch Rexroth HNF01.1A-M900-E0051-A-480-NNNN Mains Line Filter

HNF01.1A-M900-E0051-A-480-NNNN is a Bosch Rexroth IndraDrive M mains line filter designed for three-phase 380–480 VAC power to suppress EMI on IndraDrive M drives and protect the drive and surrounding circuitry from conducted disturbances. It supports a nominal current of 51 A, a maximum peak current of 77 A, and dissipates less than 91 W under continuous operation, all housed in a compact enclosure measuring 100 mm wide, 440 mm high, and 262 mm deep with a weight of 15 kg. The filter operates on 50/60 Hz mains and is specified for multiple supply grounding schemes defined in the HNF01 family, including TN-S, TN-C, and TT mains configurations, with variants that accommodate corner-grounded Delta and IT systems as applicable. This mains filter is intended for use with IndraDrive M systems to attenuate input noise, helping meet EMC requirements and contribute to stable motor control in demanding industrial environments.
