Standard Type AC and Type A Residual Current Devices (RCDs), which have been the bedrock of electrical safety for decades, are fundamentally blind to smooth DC residual currents. In the presence of such faults, these devices can become desensitized or &#8220;blinded,&#8221; failing to trip not only for the DC fault but also for the very AC faults they are meant to detect. This failure leaves personnel, equipment, and entire installations dangerously exposed.<\/p>\n\n\n\n<p>\uc774 \ud604\ub300\uc801 \ubb38\uc81c\uc5d0 \ub300\ud55c \ud655\uc2e4\ud55c \ud574\uacb0\ucc45\uc740 \uacfc\uc804\ub958 \ubcf4\ud638 \uae30\ub2a5\uc774 \uc788\ub294 \ud0c0\uc785 B RCBO(\uc794\ub958 \uc804\ub958 \ud68c\ub85c \ucc28\ub2e8\uae30)\uc785\ub2c8\ub2e4. \uc794\ub958 \uc804\ub958 \ubcf4\ud638\uc758 \ucd5c\uace0 \ud45c\uc900\uc778 \uc774 \uc81c\ud488\uc740 \ub2e8\uc21c\ud55c \uc815\ud604\ud30c AC\ubd80\ud130 \ub9e5\ub3d9 DC, \uadf8\ub9ac\uace0 \uac00\uc7a5 \uc911\uc694\ud55c \ud3c9\ud65c DC\uae4c\uc9c0 \ubaa8\ub4e0 \ubc94\uc704\uc758 \uace0\uc7a5 \uc804\ub958\ub97c \uac10\uc9c0\ud558\ub3c4\ub85d \ud2b9\ubcc4\ud788 \uc124\uacc4\ub418\uc5c8\uc2b5\ub2c8\ub2e4. \uc774 \ubb38\uc11c\ub294 \uc5d4\uc9c0\ub2c8\uc5b4, \uacc4\uc57d\uc5c5\uccb4 \ubc0f \uc870\ub2ec \uad00\ub9ac\uc790\ub97c \uc704\ud55c \ucd5c\uc885\uc801\uc778 \uae30\uc220 \uac00\uc774\ub4dc \uc5ed\ud560\uc744 \ud569\ub2c8\ub2e4. \ud575\uc2ec \uae30\uc220, \uc911\uc694 \uc560\ud50c\ub9ac\ucf00\uc774\uc158, \uc9c0\ub2a5\uc801 \uc124\uacc4\uc5d0 \ud544\uc694\ud55c \ud544\uc218 \uae30\uc900\uc744 \ub2e4\ub8f9\ub2c8\ub2e4.&nbsp;<strong>B\ud615 RCBO \uad6c\ub9e4<\/strong>&nbsp;\ub2e8\uc704\ub85c \uc124\uc815\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\uae30\uc220 \uc2ec\uce35 \ubd84\uc11d: B\ud615 RCBO\uc758 \uc815\uc758\ub294 \ubb34\uc5c7\uc778\uac00\uc694?<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"652\" src=\"https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-1024x652.png\" alt=\"\" class=\"wp-image-2413\" srcset=\"https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-1024x652.png 1024w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-300x191.png 300w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-768x489.png 768w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-1536x978.png 1536w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-2048x1303.png 2048w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-18x12.png 18w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/01\/\u5fae\u4fe1\u56fe\u7247_2026-01-16_152639_134-600x382.png 600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>To fully appreciate the superiority of Type B protection, it&#8217;s essential to understand its place in the hierarchy of residual current devices and the unique technology that sets it apart.<\/p>\n\n\n\n<p>\uba3c\uc800 \uac04\ub2e8\ud788 \uc694\uc57d\ud558\uc790\uba74, RCBO\ub294 \ub450 \uac00\uc9c0 \uac1c\ubcc4 \uad6c\uc131 \uc694\uc18c\uc758 \uae30\ub2a5\uc744 \uacb0\ud569\ud55c \ud558\ub098\uc758 \ucef4\ud329\ud2b8\ud55c \uc7a5\uce58\uc785\ub2c8\ub2e4:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\uc794\ub958 \uc804\ub958 \uc7a5\uce58(RCD \ub610\ub294 RCCB):<\/strong>\u00a0\ub204\uc804 \uc804\ub958\ub97c \uac10\uc9c0\ud558\uc5ec \uac10\uc804 \ubc0f \ud654\uc7ac \uc704\ud5d8\uc73c\ub85c\ubd80\ud130 \ubcf4\ud638\ud569\ub2c8\ub2e4.<\/li>\n\n\n\n<li><strong>\ubbf8\ub2c8\uc5b4\ucc98 \ud68c\ub85c \ucc28\ub2e8\uae30(MCB):<\/strong>\u00a0\uacfc\ubd80\ud558 \ubc0f \ub2e8\ub77d\uc744 \uac10\uc9c0\ud558\uc5ec \uc7a5\ube44 \uc190\uc0c1 \ubc0f \ud654\uc7ac\ub85c\ubd80\ud130 \ubcf4\ud638\ud569\ub2c8\ub2e4.<\/li>\n<\/ul>\n\n\n\n<p>By integrating both functions, an RCBO provides comprehensive protection for a single circuit, simplifying panel design and improving fault isolation.

drivers for the adoption of Type B protection. A Mode 3 EV charging station contains a sophisticated AC\/DC converter that can, under certain fault conditions within the vehicle&#8217;s electronics, produce a smooth DC leakage current back onto the AC supply cable. The international standard for EV charging installations, IEC 61851-1, explicitly requires that each charging point is protected against DC fault currents. This can be achieved either by using a&nbsp;<strong>\ud0c0\uc785 B RCBO 30mA<\/strong>&nbsp;\ub610\ub294 \ubcc4\ub3c4\uc758 6mA DC \uac10\uc9c0 \uc7a5\uce58(RDC-DD)\uc640 \ud568\uaed8 \ud0c0\uc785 A RCBO\ub97c \uc0ac\uc6a9\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4. \uc62c\uc778\uc6d0 \ud0c0\uc785 B RCBO\ub97c \uc0ac\uc6a9\ud558\uba74 \ub354\uc6b1 \uac15\ub825\ud558\uace0 \ud1b5\ud569\uc801\uc774\uba70 \uc548\uc815\uc801\uc778 \uc194\ub8e8\uc158\uc744 \uc81c\uacf5\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">\ud0dc\uc591\uad11 \ubc1c\uc804(PV) \uc2dc\uc2a4\ud15c<\/h4>\n\n\n\n<p>Solar power systems, particularly those using transformerless (or non-isolated) inverters, are another critical application. These inverters are directly coupled to the AC grid. In the event of an insulation failure on the DC side (the solar panels), it&#8217;s possible for DC fault current to &#8220;leak&#8221; through the inverter and onto the AC installation. This DC component can blind any upstream Type A or AC RCDs, creating a hidden danger across the entire property. Therefore, regulations and inverter manufacturer instructions almost universally require Type B protection on the AC output of the inverter to ensure safety and prevent the entire system&#8217;s protection from being compromised.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Industrial Motor Control (Variable Frequency Drives &#8211; VFDs)<\/h4>\n\n\n\n<p>\uc0b0\uc5c5 \ud658\uacbd\uc5d0\uc11c 3\uc0c1 \uac00\ubcc0 \uc8fc\ud30c\uc218 \ub4dc\ub77c\uc774\ube0c\ub294 \ucee8\ubca0\uc774\uc5b4, \ud38c\ud504, \ud32c, \uacf5\uc791 \uae30\uacc4\uc640 \uac19\uc740 \uc560\ud50c\ub9ac\ucf00\uc774\uc158\uc5d0\uc11c AC \ubaa8\ud130\uc758 \uc18d\ub3c4\uc640 \ud1a0\ud06c\ub97c \uc81c\uc5b4\ud558\ub294 \ub370 \ub110\ub9ac \uc0ac\uc6a9\ub429\ub2c8\ub2e4.

It detects everything a Type A device can, plus smooth DC residual currents up to the rated residual current (I\u0394n). This smooth DC detection is achieved through advanced dual-sensing technology\u2014typically combining a traditional core-balance transformer with an active electronic circuit such as a flux-gate sensor. This makes Type B essential for applications involving three-phase power converters, VFDs, transformerless PV inverters, and EV charging stations, where smooth DC leakage can occur. Critically, Type B protection prevents the &#8220;blinding&#8221; effect where DC components can desensitize Type A devices, potentially causing them to fail to trip even for AC faults.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">B\ud615 RCBO \ubcf4\ud638\ub294 \uc5b8\uc81c \ubc95\uc801\uc73c\ub85c \uc758\ubb34\ud654\ub418\ub098\uc694?<\/h4>\n\n\n\n<p>\uc720\ud615 B \ubcf4\ud638\ub294 \uc5ec\ub7ec \uc911\uc694 \uc560\ud50c\ub9ac\ucf00\uc774\uc158\uc5d0\uc11c \uad6d\uc81c \ud45c\uc900 \ubc0f \ud604\uc9c0 \uc804\uae30 \ucf54\ub4dc\uc5d0 \uc758\ud574 \uc758\ubb34\ud654\ub418\uc5b4 \uc788\uc2b5\ub2c8\ub2e4:<\/p>\n\n\n\n<p><strong>\uc804\uae30 \uc790\ub3d9\ucc28 \ucda9\uc804:<\/strong>&nbsp;EV \ucda9\uc804 \uc7a5\ube44\uc5d0 \ub300\ud55c \uad6d\uc81c \ud45c\uc900\uc778 IEC 61851-1\uc740 \ubaa8\ub4dc 3 \ucda9\uc804 \uc9c0\uc810\uc5d0 \ub300\ud55c DC \uace0\uc7a5 \uc804\ub958\uc5d0 \ub300\ud55c \ubcf4\ud638 \uae30\ub2a5\uc744 \uc694\uad6c\ud569\ub2c8\ub2e4. \uc774\ub294 \uc720\ud615 B RCBO \ub610\ub294 \ubcc4\ub3c4\uc758 6mA DC \uc624\ub958 \uac10\uc9c0 \uc7a5\uce58(RDC-DD)\uc640 \uacb0\ud569\ub41c \uc720\ud615 A RCBO\ub97c \ud1b5\ud574 \ub2ec\uc131\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4. \ub300\ubd80\ubd84\uc758 \uc124\uce58\uc5d0\uc11c\ub294 \ubcf4\ub2e4 \uc548\uc815\uc801\uc778 \ud1b5\ud569 \uc194\ub8e8\uc158\uc73c\ub85c \uc720\ud615 B\ub97c \uc120\ud0dd\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<p><strong>\ud0dc\uc591\uad11 \ubc1c\uc804 \uc2dc\uc2a4\ud15c:<\/strong>&nbsp;Installations using transformerless (non-isolated) inverters typically require Type B protection on the AC output circuit.
