RCCB VKL11F - Fehlerstrom-Schutzschalter
Kuangya VKL11F Typ f rccb for mixed-frequency residual-current protection in single- and three-phase systems
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; Inc = IΔc 6/10 kA (with upstream SCPD); IP20 terminals; DIN-rail EN 60715
Übersicht
The VKL11F Typ f rccb detects earth leakage including mixed-frequency components that commonly
occur with inverters, VFD-driven motors, and UPS equipment. It disconnects the circuit when residual current
exceeds the set threshold to protect people and installations against electric shock and fire hazards.
Available as 2P (single-phase) and 4P (three-phase).
