Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 424369 (model E82ZN22334B230) is a 3-phase mains RFI interference suppression filter engineered for industrial motor drive installations within the Lenze 8200 Vector accessories series. Designed specifically as a matched companion component for 22 kW 8200 Vector frequency inverters, this electromagnetic compatibility filter attenuates high-frequency noise generated by inverter switching transistors. Operating across a 3-phase AC supply voltage range of 400 V AC to 480 V AC with a continuous rated current of 48 A, the unit prevents line-conducted interference from feeding back into the facility power grid, protecting surrounding electronic devices, sensors, and control hardware.
Integrating a replacement filter into an existing control cabinet requires verifying electrical ratings and footprint alignment. The E82ZN series features a versatile mounting layout that allows positioning either directly beneath or adjacent to the corresponding 8200 Vector inverter frame size. Because this is a hardware EMC filter installed on the incoming 3-phase supply lines, putting a replacement unit into service requires no software configuration, parameter transfers, or firmware alignment. Maintenance personnel need to ensure proper terminal connections, supply phase sequence, and secure chassis grounding to maintain low-impedance attenuation. ABC Industrial Parts can assist in sourcing authentic replacement modules to restore machine protection without altering cabinet layouts.
When troubleshooting power line disruptions or high-frequency interference in an active machine installation, first-line checks should focus on mains supply stability, terminal screw tightness, and lead routing between the AC supply, filter, and 8200 Vector inverter. Persistent interference on nearby communication networks or sensors can indicate loose earth connections or electrical stress following line transients. Because internal filter element breakdowns are non-repairable in the field, replacing a compromised filter with a tested exchange component from ABC Industrial Parts offers a swift path back to stable production and full regulatory compliance.

Replacement and Spare Part Considerations
Replacing a mains filter in a Lenze 8200 Vector drive system requires matching the drive power rating and electrical network parameters. The Lenze 424369 (E82ZN22334B230) is tailored for 22 kW frequency inverters running on 3-phase 400 V AC to 480 V AC supplies at up to 48 A continuous current. Selecting an incorrect filter rating risks inadequate noise suppression or potential thermal overload during sustained operation.
Although Lenze has officially discontinued the 8200 Vector line and its associated accessories, direct-fit replacement components remain critical for maintaining existing automation infrastructure. The flexible footprint supports mounting directly under or alongside the matching inverter chassis, simplifying retrofits and minimizing machine downtime during maintenance cycles.
Frequently Asked Questions
What is the function of the Lenze 424369 mains filter?
The Lenze 424369 (E82ZN22334B230) attenuates high-frequency radio interference (RFI) generated by frequency inverters, suppressing line-conducted noise back into the 3-phase mains supply to protect surrounding equipment.
Which drive power rating matches the E82ZN22334B230 filter?
This filter is specifically sized for 22 kW 8200 Vector frequency inverters operating on 3-phase 400 V AC to 480 V AC supplies with a 48 A current load.
How is the Lenze 424369 filter mounted inside a control cabinet?
The E82ZN series footprint allows flexible cabinet installation, supporting direct mounting beneath the matching 8200 Vector inverter or alongside it.
Is software configuration needed when installing a replacement 424369 filter?
No. The 424369 is a passive electrical power filter installed on the 3-phase input lines, requiring no parameter entry, firmware alignment, or programming software.
What basic checks should be performed if mains interference persists?
Verify supply line voltage stability, inspect power cable terminations for tightness, and ensure protective earth grounding connections are secure between the mains grid, filter enclosure, and inverter frame.
