For safety in electrical systems and machines with three-phase frequency inverters, EPA GmbH has expanded its portfolio with AC\/DC sensitive residual current circuit breakers (RCCBs). With a special characteristic curve for drive technology, unwanted RCD tripping due to high leakage currents in high-frequency ranges is prevented.<\/p>\n\n\n\n

<\/div>\n\n\n\n

The EPA RCCB2 series with AC\/DC sensitive technology has a significantly higher tripping threshold than conventional models in the upper frequency range, and the residual current detection range extends far beyond the 1 kHz (type B) and 20 kHz (type B+) required by the standards and directives. EPA RCCB1 and RCCB2 detect frequencies up to 150 kHz!<\/strong><\/p>\n\n\n\n
