E82ZN22334B230 Lenze 8200-series 42A 3-Phase Mains Filter

Product Overview

The E82ZN22334B230 (E82ZN22334B230) is a high-capacity industrial EMC filter engineered specifically for the Lenze 8200-series frequency inverters. This 3-phase, 42 Amp Mains Filter B is a critical component for suppressing electromagnetic interference (EMI) and conducted emissions back into the power grid, ensuring your facility remains compliant with stringent EMC directives. In heavy industrial sectors such as automated manufacturing, material handling, and pump control, this filter protects sensitive PLC and DCS control logic from high-frequency noise generated by the inverter’s power electronics. By integrating this German-engineered component, operators significantly improve system uptime and prevent the erratic behavior of peripheral sensors and communication modules that often occurs in electrically noisy environments.

Technical Configuration

The E82ZN22334B230 utilizes a robust passive LC network optimized for 3-phase AC networks up to 500 V. As a "Filter B" variant, it is designed to meet Class B interference limits (EN 55011), allowing for longer motor cable runs while maintaining low emission levels. Its hardware architecture is built to withstand the thermal and electrical stresses of continuous 50/60 Hz operation at high current loads. The unit features heavy-duty terminal blocks for secure wiring and a low-impedance grounding plate to ensure maximum attenuation of common-mode and differential-mode noise. Although this product range has entered the Phase-Out stage, its proven reliability remains a benchmark for maintenance and retrofitting of existing 8200-series motion systems.

Technical Specifications

Technical FAQs

What is the primary difference between Filter A and Filter B in the Lenze series?

Filter B, such as the E82ZN22334B230, provides superior suppression levels compared to Filter A. It is required for applications that must meet stricter residential or light-industrial EMC standards or when using exceptionally long, shielded motor cables.

Does this filter require specific mounting orientation for cooling?

Yes. Due to its 12.64 kg mass and internal power dissipation, the filter should be mounted vertically. This allows for natural convection to move heat away from the internal inductors, ensuring the component does not exceed its thermal limits during 42 Amp peak operations.

Is this filter compatible with other inverter brands?

While technically designed for the 8200-series, it can function with other 3-phase drives provided the voltage (500 VAC) and current (42 Amps) ratings are not exceeded. However, optimal attenuation is only guaranteed when paired with the matched Lenze inverter architecture.

Engineering & Installation Guide

For effective EMI suppression, the E82ZN22334B230 must be installed as close to the inverter's power input as possible. Use a metal mounting plate with the paint removed at the contact points to ensure a low-impedance, high-frequency connection between the filter housing and the cabinet ground. Grounding via a simple green/yellow wire (pigtail) is insufficient for high-frequency noise; instead, use flat braided copper straps for the best results. Ensure that the input power lines and the filtered output lines are physically separated within the cabinet to prevent "crosstalk," where noise from the dirty input line couples back into the clean output line. In high-vibration applications, regularly inspect the terminal connections and re-torque to manufacturer specifications to prevent resistive heating caused by loose contacts.
