The Schneider Electric Acti9 iDPN Vigi is a Residual Current Breaker with Overcurrent protection (RCBO) designed mainly for residential and small commercial distribution boards. It combines three protections in one device:

• Earth‑leakage (residual current) protection
• Overload protection
• Short‑circuit protection

This means one iDPN Vigi can replace an MCB + RCCB combination on a final circuit.

What the “iDPN Vigi” name means

• iDPN → Modular single‑phase Acti9 protection device
• Vigi → Integrated residual current (earth leakage) protection
• RCBO → Residual current breaker with overcurrent protection

 In practice, the phase is protected, neutral is switched, and earth‑leakage detection is built in.

Key technical characteristics

1. Protection functions

The iDPN Vigi provides:

• Protection against electric shock(direct & indirect contact)
• Overload protection(thermal)
• Short‑circuit protection(magnetic)
• Isolation function

All in a single 1P+N device.

2. Earth‑leakage protection

Typical ratings depend on the model:

• Sensitivity: commonly 30 mA(personal protection)
• Types:
  • Type AC – detects sinusoidal AC leakage
  • Type A – detects AC + pulsating DC (recommended for modern appliances)

Residual current operation is voltage‑independent and instantaneous.

3. Overcurrent & short‑circuit protection

• Rated current (In): typically 6 A to 40 A
• Tripping curves: B or C
• Breaking capacity: 6 kA (6000 A) at 230–240 V AC
• Limitation class: 3

This makes it suitable for final circuits, not high‑fault industrial incomers.

4. Poles, size & mounting

• Configuration: 1P + N
• Width: 36 mm(4 × 9‑mm modules)
• Mounting: 35 mm DIN rail
• IP rating: IP20 (IP40 in enclosure)
• Control: Toggle with ON / OFF / fault trip indication

---

Standards & compliance

The iDPN Vigi complies with:

• IEC / EN 61009‑2‑1(RCBO standard)
• Provides isolation in accordance with IEC / EN 60947‑2

This makes it compliant with modern international wiring standards.

---

Typical applications

The iDPN Vigi RCBO is commonly used for:

• Socket‑outlet circuits
• Lighting circuits
• Water heaters
• Dedicated appliance circuits
• Residential distribution boards
• Small commercial panels

Each circuit can have individual earth‑leakage protection, so a fault on one circuit doesn’t trip the whole board.
