Chint OUVR-2 Over Voltage and Under Voltage Protector

Brand Name:Chint
Place of Origin:China
Model Number:OUVR-2
SKU: 1769744521173671936 Category: Chint MCB

Where to Use OUVR Over/Under Voltage Protector?

The Chint OUVR-2 Over Voltage and Under Voltage Protector 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

ModelOUVR
Rated Current32A - 80A
Overvoltage Cutoff275V AC (typical) - Adjustable on some models
Undervoltage Cutoff160V AC (typical)
Recovery Delay30-60 seconds (prevents rapid cycling)

Installation Location

Install the OUVR 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.

Chint OUVR-2 Self-recovery Overvoltage and Undervoltage Protector

 

1. Product Features
1.1 Preventing misoperation: Where sudden transient or temporary overvoltage occurs in the line, the protector will not generate misoperation; when the line suffers instable voltage or sudden power recovery after sudden power disruption due to loose contact or other fault, the protector will not close the circuit;
1.2 Reliable operation: Protection is characterized by inverse time lag operation with operating time≤1s;
1.3 Wide scope of voltage protection: 0~450V; in case of maximum fault voltage, the protector itself will not be damaged; Safer, impulse withstand voltage: 4kV (conforming to the safety standard of category Ⅲ electrical apparatus);
1.4 Condition indication: The protector has the LED to indicate the operating state, where green is normal voltage indication, and red is overvoltage or under voltage indication;
1.5 The product is easy for installation with cable from bottom feed;
1.6 The product only has 27mm with small size;
1.7 External modular design, DIN rail mounting.

 

2. Scope of Application

2.1 OUVR-2 self-recovery overvoltage and undervoltage protector is a new type of intelligent protection apparatus. With the modular standard design, in case of overvoltage or undervoltage of power supply line, the protector can quickly and safely break the circuit under continuous high voltage surge, avoiding the happening of an accident due to abnormal voltage entry into the terminal apparatus; when voltage resumes normal value, the protector will automatically close the circuit within the specified time to
ensure the terminal apparatus can operate normally in an unattended way.
2.2 OUVR-2 self-recovery overvoltage and undervoltage protector is applied for the users or loads of AC 230V, 50Hz and rated operating current 80A and below. It is mainly used in the household distribution box or other distribution line requiring protection.
