RCCB VFL002 - 2/4-полюсный автоматический выключатель остаточного тока

Обзор

The Kuangya VFL002 is an rccb 2 полюса (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

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

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.
