Обзор

VKL11 is a residual current circuit breaker for 4p rccb applications in three-phase boards, with a 2P
version for single-phase systems. It detects earth-leakage current and disconnects the circuit to prevent electric
shock and fire hazards caused by insulation faults. Detection classes include AC, A,
и ASi (high-immunity) to suit different load characteristics and reduce nuisance tripping.
