When an EV charger&#8217;s rectifier circuit develops a fault, it can produce a smooth DC leakage current with minimal ripple. This type of current poses a severe risk: it can magnetically saturate the toroidal transformer core in standard Type A or Type AC RCDs, effectively &#8220;blinding&#8221; them and preventing detection of even life-threatening AC faults. <a href=\"https:\/\/www.feyree.com\/blogs\/news\/rcd-types-rccb-rcbo-type-b\" rel=\"noopener\">\u5f15\u7528<\/a><\/p>\n\n\n\n<p

monitoring device, not a protective device in itself. It continuously measures DC residual current in the protected circuit and triggers an external switching device\u2014typically a contactor or the charging station&#8217;s internal relay\u2014when DC leakage exceeds 6mA. This 6mA threshold is notably lower than the 10mA minimum for Type B RCCBs, providing an additional safety margin specifically tuned to prevent upstream RCD blinding. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The RDC-DD operates according to IEC 62955 and BS IEC 62955 standards, which define performance requirements for residual direct current detecting devices used in conjunction with RCDs. When integrated into an EV charging station, the RDC-DD typically connects to the charger&#8217;s control board, which then commands the main contactor to open when a DC fault is detected, effectively disconnecting the supply. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u30bf\u30a4\u30d7A\u8ca1\u56e3<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Type A RCD in this configuration provides protection against AC sinusoidal residual currents and pulsating DC residual currents\u2014the types of faults that can occur from phase-controlled equipment and half-wave rectification. While Type A devices are blind to smooth DC currents, they remain effective for AC faults as long as they haven&#8217;t been saturated by DC contamination. This is precisely why the RDC-DD&#8217;s 6mA detection threshold is critical: it ensures disconnection before DC current reaches levels that could compromise the Type A RCD&#8217;s functionality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u6bd4\u8f03\u5206\u6790\uff1a2\u3064\u306e\u89e3\u6c7a\u7b56\u3001\u7570\u306a\u308b\u30c8\u30ec\u30fc\u30c9\u30aa\u30d5<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">\u4fdd\u8b77\u7bc4\u56f2\u3068\u4fe1\u983c\u6027<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u30bf\u30a4\u30d7B RCCB<\/strong> offers universal, single-device protection with no dependencies on external monitoring systems.

protection against DC fault currents exceeding 6mA for EV charging installations. Type A RCDs cannot detect smooth DC currents and will become &#8220;blinded&#8221; when DC saturation occurs, leaving the installation unprotected against even life-threatening AC faults.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your charging station does not have certified RDC-DD compliant with IEC 62955, you must install a Type B RCCB. This is not optional\u2014it&#8217;s a fundamental safety requirement. Field investigations have documented cases where Type A RCCBs failed to trip due to DC saturation, resulting in equipment damage, fire risk, and potential electrocution hazards. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When evaluating whether your charger has adequate DC fault protection, check the technical datasheet for explicit reference to IEC 62955 compliance and RDC-DD functionality. Marketing terms like &#8220;built-in protection&#8221; or &#8220;smart safety features&#8221; are insufficient\u2014you need documented compliance with the specific standard.
