RCBOシングルポール VAL003 / VAL003N delivers combined residual-current and overcurrent protection in a compact 1P+N form factor (5–40 A), with Type AC/A, multiple IΔn options and B/C curves for residential and commercial circuits.

概要

VAL003 and VAL003N are compact modular RCBOs designed to provide combined protection against overload, short-circuit and residual current faults on single-phase distribution branches. Both variants share the same compact 1P+N footprint and current range (5–40 A), while their rated voltage and breaking capacity differ to fit regional grids: VAL003 targets 240 V systems (up to 10 kA Icn), and VAL003N targets 120 V systems (up to 15 kA Icn). With selectable residual current types (AC / A) and multiple sensitivities (6 / 10 / 30 / 100 / 300 mA), the series suits residential, commercial and light industrial applications where space efficiency and reliable nuisance-trip control are required.

よくあるご質問

What is the difference between VAL003 and VAL003N?

They share the same 1P+N form factor and current range (5–40 A) and support both Type AC and Type A residual protections. VAL003 targets 240 V grids with up to 10 kA Icn; VAL003N targets 120 V grids with 15 kA Icn.

Which sensitivities (IΔn) are available?

6 / 10 / 30 / 100 / 300 mA. For typical socket and lighting circuits, 30 mA is most common; 6–10 mA may be used for higher touch-safety requirements; 100–300 mA are generally for special coordination scenarios per local codes.

How do I 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 (e.g., motors, transformers). Always verify with upstream protection and local standards.

Can it be used in light industrial panels?

Yes, within its ratings (1P+N, up to 40 A). For larger currents, three-phase systems, or special waveforms (e.g., EV / Type B), choose other series models accordingly.
