RCCB VKL001 - Disjuntor de corrente residual

Visão geral

The VKL001 rccb monofásico (also available for three-phase boards as 4P) detects earth-leakage
currents and trips before harm occurs, providing protection for people and installations. It is widely applied in
housing, the tertiary sector, and industry. Selection covers rated currents from 16 A to 100 A and residual
sensitivities from 10 mA to 300 mA.

Detection classes & selection

• AC class — trips for slowly increasing sinusoidal AC residual currents, whether applied slowly or suddenly.
• A class — all AC features plus tripping for pulsating DC residual currents, whether applied suddenly or increasing slowly.
• High-immunity variants (Si/G/KV) — filters against spurious tripping caused by harmonics and transient surges; stable under 8/20 μs surge of 3000 A (per datasheet note).

Tripping sensitivity & time

• 10 mA — precision instrument leakage protection and bathroom use (available on 2P/4P 16–40 A).
• 30 mA — additional protection against direct contact.
• 100 mA — coordinated with the earthing system for indirect contact protection.
• 300 mA — protection against indirect contacts and fire hazards.

• Instantaneous — tripping without intentional delay; break time under IΔn (Normal) ≤ 100 ms.
• Short time delay (Si, G, KV) — ensures any tripping at least 10 ms (10–300 ms range).
• Selective (S) — 150–500 ms, ensures discrimination with a downstream non-selective RCD.

Technical Data (full table)

Aplicativos

• Single-phase boards requiring an rccb monofásico device at 240 V~ (2P).
• Three-phase distribution at 415 V~ (4P) with coordination for 6/10 kA conditional short-circuit.
• Loads with electronics and frequent transients — use high-immunity variants (Si/G/KV) to reduce nuisance trips.
