RZF02.1-4-007

The Bosch Rexroth Indramat RZF02.1-4-007 is a high-performance component in the RZF Line Filters series designed to reduce electromagnetic noise on frequency converters within the RD 500 Series. With a Nominal Connecting Voltage of 8 x AC 380 – 480 V ± 10% and supporting Rated Power Data FUR (kW) of 1.5, 3, 4, 5.5, 7.5, this filter ensures compliant operation in residential and semi-industrial environments. Its primary function is to suppress radio interference generated by regenerative braking and high-frequency switching, enabling reliable position control and speed adjustment in induction and synchronous motors.

Featuring robust suppression characteristics, the RZF02.1-4-007 achieves noise attenuation in line with EMC directive EN 61800-3 for variable-speed drives. The enclosure meets an IP20 ingress protection rating, guarding against solid objects larger than 12.5 mm while maintaining efficient thermal performance. Designed for three-phase AC networks, it accommodates a wide pulse frequency range—typically 4 kHz, 10 kHz, and 12 kHz—without compromising filtering effectiveness. The unit’s compatibility with RD 500 intelligent drive controllers ensures seamless integration and standardized noise performance across multiple power ratings.

In addition to interference mitigation, the RZF02.1-4-007 offers versatile installation options, supporting global deployment with a nominal voltage supply of 380 – 480 V AC. Its design aligns with the EN 61800-3 standard ‘‘Variable-Speed Drives in the Second Environment,’’ certifying its suitability for domestic and light industrial settings. The filter’s durable construction and compliance with EMC standards enhance system reliability and extend service life. By incorporating this filter, engineers benefit from reduced downtime, simplified compliance testing, and improved overall drive performance in automated manufacturing and process control applications.
