VKL11 is a residual current circuit breaker for 4p rccb<\/strong> applications in three-phase boards, with a 2P
\nversion for single-phase systems. It detects earth-leakage current and disconnects the circuit to prevent electric
\nshock and fire hazards caused by insulation faults. Detection classes include \u0645\u0643\u064a\u0641 \u0627\u0644\u0647\u0648\u0627\u0621<\/strong>, A<\/strong>,
\n\u0648 ASi (high-immunity)<\/strong> to suit different load characteristics and reduce nuisance tripping.<\/p>\n
