Compact EMC Filters Handle 280A

TDK expands the B84243 series EPCOS three-line EMC filters to include 10 types for currents up to 280A. All 18 types in the series are designed for a rated voltage of 530 Vac. The components are optimized for adherence to limit values in accordance with EN 61800−3:2004+A1:2011 for motor cable lengths of up to 25m (C1) or 50m (C2). The filters’ metal cases are designed with IP20 protection and, depending on the type, have dimensions between 190 mm x 40 mm x 95 mm and 450 mm x 170 mm x 230 mm.

 

Other features of the series include low leakage current that also permits operation in a 30 mA RCD environments. For smaller, hand-operated equipment the leakage current must be below 3.5 mA. For this reason, the 3A version (B84243A8003U000) has been designed for a leakage current of 1.9 mA at 400 Vac. One important safety aspect is the short discharge time to <60V within one second for the types rated at up to 44A. Further information, datasheets are available.
