The Kuangya VFL001 is a Type A RCCB<\/strong> designed to detect sinusoidal AC and pulsating DC residual currents, providing reliable protection against electric shock and electrical fires. It also supports Type AC operation for AC-only applications. With 2P\/4P configurations, rated current from 16A to 100A, and sensitivities of 10\/30\/100\/300 mA, VFL001 fits residential, commercial and light industrial distribution boards. Popular selections include rccb 16a 30ma<\/em>, rccb 25a 30ma<\/em>, rccb 40a 30ma<\/em>, \u0648 RCCB 63A 30MA<\/em>.<\/p>\n

How it works<\/h2>\n

When the residual current exceeds the preset threshold (I\u0394n), the internal toroidal sensor and trip unit of this \u0627\u0643\u062a\u0628 \u0623 \u0631 \u0631 \u0633 \u0628<\/strong> actuate the mechanism to disconnect the circuit within the specified breaking time. Short-time delay (ASi\/G\/KV) and selective (S) characteristics are available to coordinate with upstream\/downstream devices and reduce nuisance tripping.<\/p>\n

      Installation & Selection Guide<\/h2>\n
        \n
      1. Select the pole number (2P\/4P) according to system voltage: 240 V~ (single-phase) or 415 V~ (three-phase).<\/li>\n
      2. \u0627\u062e\u062a\u0631 I\u0394n<\/strong> by application: 10\/30 mA for personal protection; 100\/300 mA for fire protection\/selectivity.<\/li>\n
      3. For high inrush or EMC-sensitive loads, consider short-time delay<\/em> (ASi\/G\/KV) or Selective S<\/em> types.<\/li>\n
      4. Coordinate with upstream SCPD to meet Inc = I\u0394c 6 kA \/ 10 kA<\/strong> requirements.<\/li>\n
      5. Observe ambient limits (\u221225\u2026+55 \u00b0C, daily avg \u226435 \u00b0C) and torque settings (2.5 N\u00b7m).<\/li>\n<\/ol>\n

        \nWhat is the difference between Type A and Type AC?<\/summary>\n

        Type AC detects sinusoidal AC only; \u0627\u0644\u0646\u0648\u0639 \u0623<\/strong> also detects pulsating DC components, which are common with modern power electronics.<\/p>\n<\/details>\n

        \nWhen should I use short-time delay or S selective types?<\/summary>\n

        Use short-time delay (10\u2013300 ms) to ride through transient leakage or inrush; use S type (150\u2013500 ms) to coordinate with downstream RCCBs and avoid nuisance tripping.<\/p>\n<\/details>\n

        \nWhat upstream protection is required?<\/summary>\n

        Select an SCPD so that the conditional residual short-circuit current rating Inc = I\u0394c<\/strong> of 6 kA or 10 kA is respected under fault conditions.<\/p>\n<\/details>\n
