Product Description:

The NFE01.1-250-006 is a single-phase mains filter produced by Bosch Rexroth Indramat within the NFE Mains Filters series. Installed between the line supply and drive components, the filter attenuates conducted interference and helps automation panels meet electromagnetic compatibility limits. It provides stable impedance for phase and neutral conductors and routes residual noise through its protective earth, minimizing disturbances that could disrupt motion controllers, PLC I/O, or sensor networks.

Electrical connection is carried out with terminals that follow the DIN 462 545 standard, ensuring consistent clamping geometry. The filter supports a maximum mains voltage of AC 230 V +10%; that tolerance allows operation on 200–230 V systems while absorbing moderate overvoltage excursions. A nominal current of 4.7 A indicates the continuous load the inductive-capacitive network can carry without excess heating. Line-to-neutral insulation is verified by a two-second pulse of 1100 VDC, and insulation from line or neutral to protective earth must withstand 2000 V at 50 Hz for the same duration. These dielectric margins limit leakage and preserve long-term filter stability under repetitive switching surges.

The enclosure carries a protection rating of IP10, so only objects larger than 50 mm can enter, which is acceptable for filters mounted inside closed cabinets. With an overall width of 54 mm and horizontal construction, the device fits alongside drives on standard DIN rails, while 5.1 mm mounting holes allow screw fixation where rail space is limited. Continuous losses are restricted to 1 W, reducing cabinet heat buildup, while a mass of 0.245 kg keeps handling simple during assembly. The single-phase layout, 10 mm² ground conductor, and specified phase orientation support straightforward, repeatable installation.
