Residual current circuit breaker (RCCB)
⚡ Acti 9 iID
The Acti 9 iID
is Schneider Electric’s Residual Current Circuit Breaker (RCCB)
used for earth‑leakage protection
in residential, commercial, and light‑industrial installations.
It does not
provide overload or short‑circuit protection — it must be paired with an MCB.
🟦 What the iID Does
- Detects residual current(L ≠ N)
- Trips instantly on leakage to prevent shock and fire
- Provides safe isolation with Acti 9 VisiSafe
- Indicates faults clearly for easy troubleshooting
🟧 Key Characteristics
- RCCB only — no overload/short‑circuit protection
- DIN‑rail modular — fits Acti 9 distribution boards
- Typical sensitivities — 30 mA (personal), 100/300 mA (fire protection)
- Wide range of poles — 2P and 4P models
- High immunity options for harsh electrical environments
🟨 Typical Applications
- Residential DBs — mandatory earth‑leakage protection
- Commercial panels — lighting, socket circuits
- Industrial auxiliaries — control circuits, small loads
- Upgrades/retrofits — replacing older ELCBs
🟩 Position in the Acti 9 Family
- iID — RCCB (leakage only)
- iDPN Vigi — RCBO (leakage + overload + short‑circuit)
- iC60N/H/L — MCBs (overcurrent only)
iID = earth‑leakage protection device
iDPN Vigi = all‑in‑one protection
iC60 = overcurrent protection
⭐ One‑line summary
The Acti 9 iID is Schneider Electric’s RCCB that provides fast, reliable earth‑leakage protection and must be paired with an MCB for full circuit protection.
