The ABG NF-KC-7 from EPA is a three-phase high-performance EMC power filter, specifically developed for applications with increased electromagnetic compatibility requirements. The device is designed without a neutral conductor and features a compact book form, enabling minimal footprint. It is intended for use in industrial and technical installations where effective suppression of disturbances in the power network is required to ensure the functionality of sensitive electronic devices.

Applications
This power filter is suitable for installations operating within a voltage range of 400 to 520 V AC and a frequency of 50/60 Hz. It is particularly suitable for machines, drives, controls, and other electronic systems that could be affected by high-frequency disturbances in the power network. The high attenuation capability in both disturbance types – symmetrical (common-mode) and asymmetrical (differential-mode) – ensures stable and disturbance-free power supply. Operating conditions range from -25 °C to +85 °C, enabling use in a variety of environments, including industrial halls or outdoor areas with controlled climate conditioning.

Functions and Equipment in Detail
The ABG NF-KC-7 provides a rated current of 7 A at an operating temperature of 50 °C. The shock-protected terminals ensure safe mounting and connection, minimizing the risk of electrical accidents. The leakage current is 1.1 mA, while the leakage current is 0.6 mA, indicating efficient and safe noise suppression. The metal housing ensures a robust and durable construction that withstands mechanical stress.

Technology Explained Simply
The function of the power filter is based on suppressing electromagnetic disturbances generated by electronic devices in the network. Symmetrical attenuation (common-mode) acts on disturbances occurring between phases and earth potential, while asymmetrical attenuation (differential-mode) reduces disturbances between individual phases and earth potential. The rated voltage is 520 VAC with a tolerance of ±10 %, allowing flexible adaptation to various network voltages. The frequency range coverage of 48 to 63 Hz covers common network frequencies in Europe and North America.

Compatibility and Accessories
The device is designed for use in three-phase systems without a neutral conductor. It is equipped with mounting brackets that enable secure installation on walls or in enclosures. The CE and UL certifications, along with standards EN 60939, UL 1283, and CSA 22.2 No. 8, confirm compliance with international safety and quality standards. The protection rating IP20 protects against finger contact and solid foreign objects, but not against water or dust.

Mounting and Installation
Mounting is done via integrated mounting brackets with holes, allowing secure anchoring to a flat surface. The shock-protected terminals facilitate safe and reliable connection of the cables. The climate category 25/085/21 (−25 °C to +85 °C) ensures reliable operation under extreme environmental conditions. Dimensions of 190 × 40 × 70 mm (L×W×H) allow compact placement in enclosures or machine cabinets.

Advantages in Operation
The ABG NF-KC-7 offers high disturbance attenuation, increasing the reliability of electronic systems. The compact design and robust metal construction ensure long service life and low maintenance requirements. The certifications and standards guarantee safe and standard-compliant integration into existing installations. Operational safety is supported by shock-protected terminals and the defined climate category.
