RCCB VFL002 - 2/4極残留電流サーキットブレーカ

概要

The Kuangya VFL002 is an RCCB 2ポール (also available as 4 pole) residual current device engineered to
protect people and installations from electric shock and fire risk due to earth-leakage faults. It offers AC, A, and
high-immunity ASi detection classes, making it suitable for residential housing, commercial buildings, and light
industrial facilities. Selection covers rated currents from 16 A to 100 A and sensitivities from 10 mA to 300 mA.

Detection classes & tripping

• AC class — trips for sinusoidal AC residual currents applied slowly or suddenly.
• A class — AC plus pulsating DC residual currents.
• ASi type — high-immunity A type (G/KV + Si behavior); filters transients/harmonics to reduce nuisance tripping.

• Break time under IΔn (Normal): ≤ 100 ms
• Short time delay: 10–300 ms (ASi, G, KV types)
• Selective S type: 150–500 ms

主な特徴

• Configurations: 2P / 4P with top or bottom supply, any mounting position
• Rated current In: 16, 25, 32, 40, 63, 80, 100 A
• Rated sensitivity IΔn: 10 mA (2P/4P 16–40 A), 30 mA, 100 mA, 300 mA
• Rated voltage Ue: 2P: 240 V~; 4P: 415 V~   |   Ui: 500 V |   fn: 50/60 Hz
• Rated residual making & breaking (IΔm): 500 A (In 16–40 A); 630 A (63 A); 800 A (80 A); 1000 A (100 A)
• Inc = IΔc (conditional short-circuit): 6 kA or 10 kA (with upstream SCPD coordination)
• Impulse withstand Uimp: 6 kV (1.2/50 μs); 誘電テスト： 2.5 kV / 1 min
• 端子保護： IP20; fault current indicator provided

よくあるご質問

When do I choose 2P vs 4P?

Use 2P for single-phase 240 V~ systems and 4P for three-phase 415 V~ systems.

What sensitivity should I select?

10/30 mA for additional personal protection; 100/300 mA for fire protection and selectivity.

How to coordinate conditional short-circuit rating?

Use an upstream breaker/fuse so the installation respects Inc = IΔc (6 kA / 10 kA) under fault conditions.
