The Kuangya VFL002 is an RCCB 2\u30dd\u30fc\u30eb<\/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
