RCBO \uc2f1\uae00 \ud3f4<\/strong> VKL003 \/ VKL003N is a compact 1P+N residual-current circuit breaker with overcurrent protection, rated 5\u201340 A with Type AC\/A, multiple sensitivities, and B\/C curves for residential and commercial distribution circuits.<\/p>\n

\n

\uac1c\uc694<\/h2>\n

VKL003 and VKL003N provide combined protection against overload, short circuit, and
\nresidual current faults on single-phase branches. Both share the same 1P+N form factor
\nand current range (5\u201340 A). VKL003 targets 240 V<\/strong> systems with breaking capacity
\n\ucd5c\ub300 10 kA<\/strong>, while VKL003N is optimized for 120 V<\/strong> \uc2dc\uc2a4\ud15c
\n15 kA<\/strong> Icn. Type AC and Type A options plus five sensitivity levels enable precise
\ncoordination across lighting and socket circuits.<\/p>\n<\/section>\n

      \n

      Both are 1P+N, 5\u201340 A with Type AC\/A and five I\u0394n levels. VKL003 is for 240 V (up to 10 kA Icn); VKL003N is for 120 V (15 kA Icn).<\/p>\n<\/div>\n<\/details>\n

      \nWhen should I choose curve B or curve C?<\/summary>\n
      \n

      Use curve B (3\u20135\u00d7In) for resistive\/lightly inductive loads; use curve C (5\u201310\u00d7In) for circuits with higher inrush such as motors or transformers.<\/p>\n<\/div>\n<\/details>\n
