The modern components in automation technology (such as frequency inverters, line filters, switched-mode power supplies, shielded motor cables, etc.) generate system-related leakage currents. These so-called \u201coperational\u201d leakage currents are recognized by the RCD protective devices as residual currents and so often lead to unsafe operating conditions or to shutdown of the system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The residual current device (RCD) cannot distinguish between operational leakage currents and real residual currents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In order to avoid undesired tripping of the residual current circuit breaker, a device is required that can compensate the capacitive leakage currents with a frequency of 50 Hz.<\/p>\n<\/div><\/div>\n\n\n\n<div style=\"height:var(--wp--preset--spacing--80)\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-media-text has-media-on-the-right is-stacked-on-mobile\"><div class=\"wp-block-media-text__content\">\n<h2 class=\"wp-block-heading\">The solution<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The selectable (5 or 11 mA) leakage current compensation device LEAKCOMP\u00ae 1C was specially developed for this purpose. It is used in electrical systems or machines in which (mostly single-phase) devices with an integrated EMC filter have to operate on residual current devices (RCD) or residual current circuit breakers (RCCB) with rated residual currents I&lt;sub>\u2206n&lt;\/sub> = 30 mA or higher.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The LEAKCOMP\u00ae 1C compensates the operational leakage currents that occur in the system\/machine and thus prevents false tripping of residual current protective devices, which are caused by excessively high 50 Hz leakage currents. This functionality is given with all commercially available RCCB of types A, F, B and B + (short-time delayed (KV) version recommended).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The level of the 50 Hz compensation current is 5 mA and can be increased to 11 mA via a wire bridge. If the compensation current is not sufficient to compensate for the full leakage current, further LEAKCOMP\u00ae 1C can be connected in parallel easily.<\/p>\n<\/div><figure

The EPA LEAKCOMP\u00ae 1C is used to compensate the capacitive leakage currents with a frequency of 50 Hz, which result from EMC filter measures for single-phase loads (e.g. power supplies, frequency inverters, UPS, lights, line filters, Y capacitors etc.).
