Product Description:
The HNF01.2D-M900-R0094-A-480-NNNN is a mains filter produced by Bosch Rexroth Indramat and included in the HNF Mains Filters series. Installed between the plant mains and drive controllers, it suppresses conducted electromagnetic interference and provides a stable return path for regenerated energy during motoring and braking cycles. By conditioning three-phase power lines, it helps large multi-axis installations meet electromagnetic compatibility requirements while reducing unwanted noise on the supply network. This placement also supports more stable operation of connected drive components in cabinets that serve several coordinated axes.
Rated for a continuous line current of 94 A, the filter supports sizable inverter groups without core saturation. Its enclosure carries an IP20 degree of protection, so it is intended for installation inside a control cabinet where basic touch protection is sufficient. The filter accepts 3 × AC 400–480 V ±15/+10%, 50/60 Hz, which suits common plant supplies without separate voltage adaptation. Compliance with emission class C2 - DIN EN 61800-3 over an extended frequency band helps keep switching harmonics within prescribed limits. Capacity for 15 axes, max. cable length 900 m supports long motor leads in distributed machine layouts without exceeding the intended interference limits.
Design version 2 incorporates an updated damping network and is intended for regenerative devices only. The internal series identifier 01 matches the filter elements to the associated power sections. Low-loss inductors and high-grade film capacitors help minimize leakage current while balancing differential-mode and common-mode attenuation. Additional screw terminals support daisy-chain wiring so adjacent drives can share the same protective earth node and use cabinet space more efficiently.
