VKL003/VKL003N RCBO - 단극 + 중성(1P+N) 5-40A
RCBO 단극(1P+N) RCBO for residential & commercial branches, 5-40A에서, 커브 B/C.
유형 AC / 유형 A, 감도 IΔn 6 / 10 / 30 / 100 / 300 mA; Icn up to 10 kA @ 240 V (VKL003) / 15kA @ 120V (VKL003N).
SEMKO / UKCA / CE / SAA certified; electrical & mechanical endurance 2,000 cycles; DIN-rail mounting with front test button.
RCBO 싱글 폴 VKL003 / VKL003N is a compact 1P+N residual-current circuit breaker with overcurrent protection, rated 5–40 A with Type AC/A, multiple sensitivities, and B/C curves for residential and commercial distribution circuits.
개요
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
최대 10 kA, while VKL003N is optimized for 120 V 시스템
15 kA Icn. Type AC and Type A options plus five sensitivity levels enable precise
coordination across lighting and socket circuits.

자주 묻는 질문
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.
