Where to Use Chint Over/Under Voltage Protector?

The CHINT OUVT-X3 Over and Under Voltage Release for NXB-125 MCB is a self-recovery overvoltage and undervoltage protector designed to protect household appliances and electrical equipment from damage caused by abnormal grid voltages. When voltage exceeds safe limits (typically >275V or <160V), the device automatically disconnects power and reconnects when normal voltage returns.

Why You Need Voltage Protection

Overvoltage Protection - Prevents damage to appliances from high voltage (common after power restoration)
Undervoltage Protection - Prevents motor burnout from low voltage/brownouts
Automatic Recovery - Self-resetting when voltage returns to normal, no manual intervention
Delay Function - Prevents rapid on/off cycling during voltage fluctuations

Technical Specifications

Model	Chint
Rated Current	32A - 80A
Overvoltage Cutoff	275V AC (typical) - Adjustable on some models
Undervoltage Cutoff	160V AC (typical)
Recovery Delay	30-60 seconds (prevents rapid cycling)

Installation Location

Install the Chint at the main incoming position of the distribution board, downstream of the main breaker. This provides whole-house protection. The device mounts on standard 35mm DIN rail alongside MCBs.
