The Kuangya VFL002 is an \u0639\u0645\u0648\u062f rccb 2<\/strong> (also available as 4 pole) residual current device engineered to
\nprotect people and installations from electric shock and fire risk due to earth-leakage faults. It offers AC, A, and
\nhigh-immunity ASi detection classes, making it suitable for residential housing, commercial buildings, and light
\nindustrial facilities. Selection covers rated currents from 16 A to 100 A and sensitivities from 10 mA to 300 mA.<\/p>\n

          10\/30 mA for additional personal protection; 100\/300 mA for fire protection and selectivity.<\/p>\n<\/details>\n

          \nHow to coordinate conditional short-circuit rating?<\/summary>\n

          Use an upstream breaker\/fuse so the installation respects Inc = I\u0394c<\/strong> (6 kA \/ 10 kA) under fault conditions.<\/p>\n<\/details>\n
