Product information for EPA 50275407:
The ABG NF-DAR-50-3 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. It is designed for use in industrial and commercial electrical installations, where increased leakage currents caused by electronic devices, such as frequency converters or LED lighting, can impair the function of residual current circuit breakers (type B/B+). The filter thus enables the safe and reliable use of these protective devices in installations that would otherwise be incompatible due to leakage currents.
Applications
The filter is used in electrical installations where electronic loads with high leakage currents in the high-frequency range occur. This includes installations with frequency converters, electronic ballasts, LED lighting systems, or other non-linear loads. The reduction of leakage currents by up to 90 % ensures that residual current circuit breakers type B/B+ do not trip unnecessarily, thereby maintaining the safety of the installation. It is intended for indoor use, as the protection class IP20 does not provide protection against contact or moisture in outdoor environments.
Functions and Equipment in Detail
The ABG NF-DAR-50-3 reduces leakage currents in the frequency range of 2 to 16 kHz, which is typical for disturbances caused by electronic devices. The reduction is achieved by absorbing high-frequency disturbances in the network, thereby reducing the interference currents flowing through the earthing system. This is particularly important to maintain the function of residual current circuit breakers type B/B+, which are sensitive to such disturbances. The filter is rated for a nominal current of 50 A and can therefore be used in installations with corresponding load capacity.
Technology Explained Simply
The filter operates in the field of electromagnetic compatibility (EMC) and uses passive components to absorb high-frequency disturbances. The absorption is achieved by integrating filter components specifically designed for the frequency range of 2 to 16 kHz. The nominal voltage is 520 VAC (±10 %) for a three-phase supply, covering a frequency range of 48 to 63 Hz. The metal housing construction ensures a robust mechanical structure and provides sufficient protection against mechanical damage indoors. The protection class IP20 means the filter is protected against contact with fingers or similar objects, but not against water or dust.
Compatibility and Accessories
The ABG NF-DAR-50-3 is specifically designed for combination with EPA EMC network filters. This combination enables more comprehensive disturbance reduction, especially in complex installations where multiple disturbance sources are present. The use with other EMC filters is not explicitly mentioned, but combinability with EPA products is explicitly stated. The certifications CE and UL, as well as standards EN 60939, UL 60939-3, CSA 22.2 No. 8 and RoHS, confirm compliance with international safety and environmental standards.
Mounting and Installation
The filter is integrated into the electrical installation, typically near the load or distributor, where leakage currents are strongest. Mounting is done in an enclosure or distribution unit, taking into account the dimensions of 158 × 114 × 92 mm (L×W×H). Installation requires compliance with electrical standards and correct wiring according to the circuit diagrams.
Advantages in Operation
By reducing leakage currents by up to 90 %, the reliability of residual current circuit breakers type B/B+ in installations with electronic loads is increased. This leads to improved operational safety and prevents unnecessary shutdowns. The use of the filter thus enables more efficient and safer operation of the electrical installation, especially in environments with many non-linear loads. Compliance with international standards and certifications ensures safe and standard-compliant integration into existing systems.
