Lenze E82ZN22334B230 Mains Filter B – Ensuring Electromagnetic Compatibility in Industrial Automation

The Lenze E82ZN22334B230 is a high-quality Mains Filter B designed to enhance electromagnetic compatibility (EMC) compliance in demanding industrial automation environments. Engineered to minimize electromagnetic interference (EMI), this mains filter ensures a stable and clean power supply, which is critical for the reliable operation of sensitive electronic equipment such as frequency inverters, servo drives, and control systems.

Manufactured in Germany by Lenze, a trusted name in industrial automation technology, the E82ZN22334B230 provides robust noise suppression to comply with stringent EMC standards, including EN 55011 limit value class B and EN 133200. This compliance ensures that the filter effectively reduces both conducted and radiated emissions, preventing disturbances that could impact other equipment in the same facility or the broader electrical network.

With a rated current capacity of 3 × 42A and designed for use with a voltage rating of 3 × 500V AC, this mains filter is suitable for a wide range of three-phase industrial power supplies operating at 50 or 60 Hz frequencies. Its inductance of 3 × 0.7 mH contributes to effective attenuation of high-frequency noise components, which commonly arise from power switching devices and variable frequency drives.

One notable feature of the E82ZN22334B230 is its low voltage drop, measured at only 9V at a current of 42A and 50 Hz. This minimal voltage drop ensures efficient power delivery to connected equipment without significant losses, maintaining optimal system performance and energy efficiency.

From a mechanical standpoint, the filter is designed for secure and reliable installation, with torque specifications carefully defined for mounting screws and terminal connections. The filter accommodates M4 screws tightened to 2.5 Nm and M5 screws to 3.0 Nm, while terminal connections require torque values between 2.0 and 4.0 Nm. These precise torque requirements help maintain electrical contact integrity and ensure safety during operation.

Additionally, the Lenze E82ZN22334B230 is certified to meet CE and UL standards (UL file number E219022), offering assurance of its quality and safety for global industrial applications.

In summary, the Lenze E82ZN22334B230 Mains Filter B is a vital component for ensuring EMC compliance and stable power quality in industrial automation systems. Its robust design, effective EMI reduction, and adherence to international standards make it an essential solution for protecting sensitive electronic devices and maintaining smooth, uninterrupted operation in complex industrial environments.
