Обзор
VKL003 and VKL003N provide combined protection against overload, short circuit, and
residual current faults on single-phase branches. Both share the same 1P+N form factor
and current range (5–40 A). VKL003 targets 240 V systems with breaking capacity
up to 10 kA, while VKL003N is optimized for 120 V systems with
15 кА Icn. Type AC and Type A options plus five sensitivity levels enable precise
coordination across lighting and socket circuits.

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
What is the difference between VKL003 and VKL003N?
Both are 1P+N, 5–40 A with Type AC/A and five IΔn levels. VKL003 is for 240 V (up to 10 kA Icn); VKL003N is for 120 V (15 kA Icn).
When should I choose curve B or 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.
What is the advantage of an rcbo single pole form factor?
The compact 1P+N layout saves rail width while providing full residual and overcurrent protection—ideal for lighting and socket branches.
