RCCB VKL11 (A/AC/ASi) - Interruttore automatico differenziale
The Kuangya VKL11 4p rccb provides fast disconnection on earth-leakage to protect people and installations
2P / 4P; In 16–100 A; IΔn 10/30/100/300 mA; Ue 240 V (2P) / 415 V (4P); Ui 500 V; 50/60 Hz
High-immunity ASi option to reduce nuisance trips; DIN-rail EN 60715; IP20 terminals
Panoramica
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,
e ASi (high-immunity) to suit different load characteristics and reduce nuisance tripping.
