Lenze E82ZZ75112B210 RFI Filter – 3x500V 3.4A Mains Noise Filter
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZZ75112B210 is a three-phase RFI footprint filter engineered for line noise suppression in Lenze 8200 vector frequency inverter systems. Designed to attenuate high-frequency radio frequency interference generated by variable speed drive switching operations, this EMC filter prevents electrical noise from conducting back into the main AC power grid and disturbing nearby sensitive control equipment. Operating at voltages up to 3x 500 V AC across 50/60 Hz mains supplies, the unit carries a continuous current rating of 3.4 A. Its integrated footprint construction enables convenient sub-assembly mounting directly underneath matching 8200 vector drive chassis, significantly saving valuable panel surface area inside industrial control enclosures.
Electrical integration is handled through heavy-duty screw terminals that provide low-resistance, vibration-resistant phase connections for incoming mains power and drive output feeds. Putting a replacement filter into service is a straightforward mechanical and electrical swap that does not require parameter entry, software setup, runtime licensing, or drive firmware adjustments. Maintenance technicians must ensure correct phase matching and proper ground bonding during installation to maintain optimal electromagnetic compatibility across factory automation, packaging machinery, and material handling systems. ABC Industrial Parts can supply replacement units to assist teams in keeping existing 8200 vector equipment fully compliant without needing a complete system overhaul.
Because the E82ZZ75112B210 is a passive electrical filter component without internal status LEDs, digital diagnostic displays, or fieldbus telemetry, line distortion or disturbance conditions are observed through drive trip indications or panel-level power monitoring. First-line troubleshooting for suspected line noise issues includes checking screw terminal connection tightness, verifying earth wire grounding integrity, and inspecting the filter housing for signs of thermal stress. Internal component breakdown within a passive noise filter cannot be serviced in the field; replacing the filter assembly with a tested unit from ABC Industrial Parts offers the most reliable path to restoring system operation and preserving line quality.

Replacement and Spare Part Considerations
Replacing an existing Lenze E82ZZ75112B210 requires matching the 3-phase supply rating up to 500 V AC and continuous current capacity of 3.4 A to maintain correct EMC filter performance without causing thermal or electrical overloading. Utilizing the exact model number ensures physical compatibility with the footprint mounting template underneath Lenze 8200 vector variable frequency drives, preserving enclosure layout efficiency.
As a passive component, installing a replacement unit requires no drive re-parameterization, software uploading, or option card configuration. Servicing involves safely isolating power, disconnecting phase wiring at the screw terminals, unmounting the damaged filter, and securing the replacement. Proper terminal torque and earth ground connections must be confirmed during reassembly to ensure effective high-frequency noise attenuation.
