Product Description:

The NFE01.1-230-008 mains filter is produced by Bosch Rexroth Indramat as part of the NFE Mains Filters series. The module is installed between the incoming utility feed and the power input of drive controllers, servo amplifiers, or PLC power supplies. Its purpose is to attenuate radio-frequency interference generated by switching devices and to prevent external disturbances from coupling into sensitive industrial automation electronics. By reducing conducted noise at the cabinet entry point, it helps nearby control hardware remain stable during normal machine operation. Placed ahead of the load, it also limits the spread of switching noise onto the supply line and reduces the chance of interference with other devices on the same branch circuit.

Electrically, the filter handles single-phase supplies at a nominal line potential of 230 V AC, so no additional transformer is required in standard European or 240 V North American installations. The magnetic elements are rated for a continuous load of 8 A, allowing the unit to support small drive groups without core saturation during steady operation. Thermal and dielectric clearances are enclosed within a chassis that carries an IP10 rating, which provides basic finger protection while leaving airflow open around the housing. Terminals accept protective ground conductors up to 10 mm², helping maintain a low-impedance bond to the cabinet grounding system. This arrangement suits compact control panels where line filtering and simple wiring access are both required.

For transient demands, the design tolerates 1.5 × IN for 1 min/h, allowing short regeneration or motor-start surges without overheating the windings. All current figures are referenced to an ambient temperature of 45 °C, so the published rating applies to typical control-cabinet conditions when ventilation is adequate. Insulation strength is verified by a test of 2800 VDC for two seconds between line or neutral and ground, which helps the unit withstand routine dielectric checks and brief overvoltage events. The filter is manufactured by Bosch Rexroth Indramat for continuous-duty use in industrial power distribution assemblies. This makes it suitable for cabinets that contain sensitive feedback, control, and communication electronics near the power entry section.
