Product information for EPA 52240003:
The OC/3 snap-on ferrite ring from EPA is a ring core made of MnZn ferrite, specifically designed for retrofitted installation on cables without cutting. It is used for suppressing high-frequency conducted interference, i.e. HF noise suppression, particularly on motor cables, signal lines and power supplies. The opening width is Ø 50 mm, enabling installation on cables with a diameter up to 50 mm. The ring is designed for motors with a power up to 45 kW and is therefore suitable for industrial applications in the medium power range.
Applications
The ferrite ring OC/3 is primarily used in industrial environments where electromagnetic interference can occur due to motors, frequency converters or other electrical devices. It serves to reduce high-frequency interference that is coupled into power networks or other devices via cables. This is particularly important in systems with sensitive electronics, such as controls or communication systems, to ensure stable and interference-free operation. The application is typically on motor cables, but also on other lines that may transmit interference.
Functions and equipment in detail
The ring core is made of MnZn ferrite, a material with high magnetic properties in the high-frequency range, which can effectively dampen interference. Installation is done via a snap-lock mechanism, enabling simple and quick attachment without tools. Additionally, an integrated mounting foot is provided, which can be fastened to a solid surface using four holes with a diameter of Ø 5.0 mm. This ensures secure and vibration-resistant mounting, especially in industrial environments with mechanical stress.
Technology explained simply
HF noise suppression is achieved through inductive impedance increase in the high-frequency range. The ferrite ring generates an inductive impedance that increases with rising frequency, thus effectively damping interference in the MHz range. The specified inductance of 15.4 µH × turns² describes the magnetic property of the core depending on the number of turns – the more turns, the higher the inductance. The attenuation is 16.5 dB at a frequency of 500 kHz, representing a significant reduction in interference power. The ring dimensions are 150 × 55 × 112 mm (L×W×H), and the weight is 0.7 kg.
Compatibility and accessories
The ferrite ring OC/3 is designed for motors up to 45 kW and is therefore suitable for drives in the industrial medium power range. It is designed for installation on cables with a maximum diameter of 50 mm. The ring is used without additional components – no further parts or tools are required for installation. Mounting is done via the integrated snap-lock and the mounting foot, which can be attached to a solid surface.
Installation and mounting
Installation is done without cutting the cable: the ring is opened, slid over the cable, and closed using the snap-lock. The mounting foot is fastened to a suitable surface, such as a machine frame or enclosure, using screws. The four holes with Ø 5.0 mm allow for secure mounting. Installation is therefore quick and can be done without special tools, simplifying maintenance and servicing.
Advantages in operation
Using the OC/3 snap-on ferrite ring reduces electromagnetic interference that can cause malfunctions in controls, communication systems or other sensitive devices. The simple installation without cable cutting enables quick installation even retroactively, without having to shut down the system. The robust construction with mounting foot ensures durable and vibration-resistant fastening, which is important in industrial environments. HF noise suppression improves signal quality and contributes to the overall stability of the system.
