ANFCB – Auto Neutral Failure Circuit Breaker
Neutral Monitoring | Automatic Isolation | Enhanced Electrical Safety
The Auto Neutral Failure Circuit Breaker (ANFCB) is an advanced protection device designed to Monitor and Disconnect Power Supply in case of Neutral Failure or Disconnection in three-phase systems. It protects sensitive equipment from Dangerous Phase-to-Neutral voltage Imbalance, overvoltage, and potential electrical hazards.
ANFCB is Critical for Modern LT Panels, especially in TNEB Metering Systems, multi-tenant buildings, and commercial/industrial setups where Neutral Integrity is vital.
⚙️ Key Features
- Auto detection of neutral loss or float condition
- Instant trip to isolate the supply and protect connected loads
- Works in both EB and DG modes
- Prevents overvoltage damage to single-phase loads
- Visual and audible indication for neutral fault
- Built-in auto-reset or manual reset option
- Rugged design for continuous operation
- Compatible with standard LT panel designs
- Customizable trip voltage and delay settings
