Neutral Failure Circuit Breaker
NFCB safeguards appliances and equipment from overvoltage due to neutral failure—common in aging, theft-prone, or faulty electrical setups. Using advanced microcontroller tech, it detects and disconnects abnormal voltage conditions, then auto-resets once power stabilizes.
- Protects TVs, fridges, air conditioners, and home wiring
- Trips instantly on 440V surge (caused by neutral loss)
- Prevents appliance burnout, fire hazards, and costly repairs
- Ideal for homes, apartments, and villas on 3-phase supply
- Ensures safe operation of machinery, motors, and lighting
- Shields critical systems from neutral disconnection effects
- Maintains uninterrupted workflow by isolating faulty lines
- Essential for factories, shops, offices, and warehouses
- High voltage cut-off (programmable, e.g., 295V)
- Auto/Manual reset modes
- LED indicators & fuse protection
- Supports unbalanced loads
- Built-in safety for phase imbalance & surge conditions
- Corrects the RYB Phase Sequence, whenever the sequence is changed or reversed.
- For Three Phase UPS, during sequence changed or reversed, UPS will start use the battery power & Battery
- May become empty within half or one hour. So the entire operations and server failure shall be happened
- Suffering or disturbed because of AC. Failure
- Avoid damages during Phase sequence changes or reversal
- Certified by ETDC (Electronic Test & Development Center) Govt. of India
- No break downs of lifts, Machineries, UPS, 3 Ph. Air conditioner or any motors or 3-phase system due to the change in sequence
