Product information for EPA 50275456:
The ABG NF-DAR-25-3 from EPA is a three-phase leakage current reduction filter, specifically developed for reducing high-frequency leakage currents in the range of 2 to 16 kHz. The filter reduces leakage currents by up to 90 %, which is particularly beneficial in installations with elevated leakage currents. This reduction enables the use of residual current circuit breakers of type B or B+, which would otherwise not function reliably due to excessive leakage currents. The filter is designed for use in industrial and commercial electrical installations where high electromagnetic compatibility (EMC) and reliable protection switch operation are required.
Applications
The ABG NF-DAR-25-3 is used in installations where electronic devices or frequency converters generate high leakage currents, for example in manufacturing industry, building technology, or systems with variable speed drives. Reducing leakage currents ensures that residual current circuit breakers do not trip unnecessarily, thereby increasing operational safety. The filter is designed for use in 3-phase networks and is particularly suitable for installations operating with frequency converters, LED lighting, or other non-linear loads.
Functions and Equipment in Detail
The filter reduces leakage currents in the frequency range of 2 to 16 kHz, which is typical for high-frequency disturbances caused by electronic circuits. The reduction is achieved through special absorption and filtering elements inside the housing. The rated current is 25 A, making it suitable for medium to large installations. The rated voltage is 520 VAC (±10 %), with operation possible in the voltage range of 400 to 520 V AC at 50/60 Hz. The network frequency must be within the range of 48 to 63 Hz to operate the filter correctly.
Technology Explained Simply
The leakage current reduction filter works by absorbing and damping high-frequency interference currents that occur in the network. These interference currents are often generated by fast switching operations in electronic devices. The filter ensures that these disturbances do not return to the network, thus preventing interference with the function of residual current circuit breakers. The protection class IP20 means the filter is protected against contact with fingers or similar objects, but not against water or dust. The metal housing provides mechanical stability and good protection for internal components.
Compatibility and Accessories
The ABG NF-DAR-25-3 is compatible with EPA EMC power filters, enabling additional interference suppression. This combination can be used in installations with particularly high EMC requirements. Standards EN 60939, UL 60939-3, and CSA 22.2 No. 8 ensure compliance with international safety and performance requirements. Additionally, the device complies with the RoHS directive, ensuring the use of materials free from hazardous substances. The CE and UL certifications confirm compliance with required safety standards.
Mounting and Installation
The filter is installed in the electrical network, typically between the power supply and the load generating leakage currents. Mounting is done in an enclosure or distribution board, taking into account the dimensions of 115 × 80 × 60 mm (L×W×H). Installation does not require special tools or additional accessories, as the filter is standardly designed for mounting in enclosures. Electrical connections are made via the designated terminals, rated for the nominal current of 25 A.
Operational Advantages
By reducing leakage currents by up to 90 %, the reliability of residual current circuit breakers during operation is increased. This prevents false tripping, which could lead to operational interruptions. Using the filter thus enables safe and continuous power supply in installations with electronic loads. Compliance with standards and certifications ensures safe and reliable performance in industrial applications. Compatibility with EMC power filters offers additional flexibility in adapting to specific requirements.
