VRL01 / VRL02 / VRL03 RCBO - 単極 + ニュートラル (1P+N) 6-50A
rcbo single pole (1P+N) modular RCBO for single-phase branches, In 6–50A, tripping curves B/C.
タイプAC / タイプA, sensitivities IΔn 10 / 30 / 100 / 300 mA; Icn 6 kA / 10 kA @ 240 V50/60 Hz。
Certified SEMKO / UKCA / CE; standard IEC/EN 61009-1; front test button, DIN-rail mounting.
RCBOシングルポール VRL01 / VRL02 / VRL03 integrates residual-current and overcurrent protection in a compact 1P+N format, rated 6–50 A for 240 V, 50/60 Hz systems with Type AC/A and multiple IΔn options.
概要
The VRL01 / VRL02 / VRL03 family is designed for single-phase distribution branches where
reliable residual-current protection and coordinated overcurrent performance are required.
Each variant shares the same 1P+N footprint and broad current range up to 50 A, with
selectable tripping curves (B/C), multiple residual sensitivities, and high breaking
capacity options (6/10 kA) to match fault levels on 240 V systems.

よくあるご質問
Do VRL01, VRL02 and VRL03 differ in core protection features?
All three share the same 1P+N format, 6–50 A range, Type AC/A residual options and B/C curves. They are part of the same platform with high breaking-capacity options (6/10 kA) for 240 V systems.
Which sensitivity (IΔn) should be used for sockets and lighting?
30 mA is most common for socket/lighting circuits. 10 mA is for higher touch-safety; 100/300 mA may be used per coordination and local code requirements.
How to choose between curve B and curve C?
Use curve B (3–5×In) for resistive/lightly inductive loads; use curve C (5–10×In) for circuits with higher inrush such as motors or transformers.
