RCCB VKL11 (B/B+) - Disjuntor de corrente residual
The Kuangya VKL11 b type rccb provides residual-current protection with Type B/B+ detection suitable for AC and DC leakage conditions
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
Uimp 4/6 kV (per variant); Inc = IΔc 6/10 kA (with upstream SCPD); IP20 terminals; DIN-rail EN 60715
Visão geral
VKL11 (B/B+) is a b type rccb designed to disconnect the circuit when residual current exceeds
the threshold, helping prevent electric shock and fire hazards due to insulation faults. The Type B/B+ variants
are suitable for leakage containing smooth DC and higher-frequency components often present with frequency
converters, inverters, PV/EV equipment, and VFD-driven motors. Pole options include 2P for single-phase and
4P for three-phase systems.
