Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 394215 (model EZF3_024A001) is a 3-phase EMC/RFI mains filter within the Lenze Mains Filters and Inverter Accessories family, engineered for noise suppression in industrial drive installations. Designed for operating voltages up to 480 V AC with a continuous rated current of 24 A, this component attenuates conducted high-frequency electrical noise generated by switching power transistors. It is primarily utilized alongside frequency inverters such as the Lenze 8200 series to maintain power quality and comply with European electromagnetic compatibility standards EN 61800-3 and EN 55011 across automotive manufacturing, material handling, packaging, and textile machinery.
Integrating or replacing the unit involves standard 3-phase line and load wiring connections between the incoming power supply and the frequency inverter. As a passive interference suppression filter, the Lenze 394215 requires no software parameters, firmware configuration, or programming setup to function. Its footprint housing construction allows it to be mounted directly underneath a compatible inverter drive or mounted laterally alongside it inside the control cabinet, saving enclosure space and keeping power interconnects short. When replacing an existing filter or refurbishing a cabinet drive assembly, ABC Industrial Parts can assist in supplying fully verified replacement units to maintain production uptime.
Because the filter operates as a passive hardware component without built-in LEDs or diagnostic displays, verifying state and performance relies on standard electrical checks. Initial inspection should focus on confirming proper phase continuity, verifying operating line voltage within the 0 to 480 V AC range, checking terminal connections for correct torque, and ensuring low-impedance protective earth grounding. Internal breakdown, insulation degradation, or shorted components are not field-serviceable and require complete filter replacement. ABC Industrial Parts can supply tested replacement units or exchange options to quickly restore EMC compliance and protect sensitive control electronics.

Replacement and Spare Part Considerations
When selecting a replacement mains filter for an existing installation, it is critical to match the exact current rating and mains voltage specifications. The Lenze 394215 (EZF3_024A001) provides a continuous 24 A current capacity at up to 480 V AC across 3 phases. Installing a filter with lower current ratings can result in thermal overload or nuisance trips during peak drive operations.
Physical layout requirements must also be verified during replacement. The footprint design allows the filter to be positioned directly under compatible drive units, such as the Lenze 8200 series, or attached side-by-side on the enclosure backplate. Ensuring correct earthing strap installation and short cable runs between the filter output terminals and the drive input is essential to preserve full high-frequency attenuation performance.
