Chint OUVR-2N80A self-resetting over-voltage and under-voltage protector specially designed

   Chint OUVR-2N80A is a self-resetting over-voltage and under-voltage protector specially designed for households and small commercial premises. It is mainly used to monitor circuits and protect them from damage caused by abnormal voltage.

 I. Core Parameters and Functions1. Electrical Specifications

- **Rated Voltage**: 230V AC (single-phase), with a frequency of 50Hz.

- **Rated Current**: 80A, suitable for circuit protection of high-power loads (such as air conditioners, water heaters, etc.).

- **Pole Number**: 1P+N design, which can protect both the live wire and neutral wire simultaneously. The straight-through design of the neutral wire ensures safety.

- **Over-Voltage Protection Threshold**: 275V±5V. The circuit will be automatically cut off when the voltage continuously exceeds this value.

- **Under-Voltage Protection Threshold**: 161V±5V. The circuit will be automatically disconnected when the voltage continuously drops below this value.

- **Recovery Range**: When the voltage returns to 196-253V, the protector will automatically reset and restore power supply within 30 seconds ±10 seconds.

2. Response and Durability

- **Operating Time**: ≤1 second, which can quickly cut off abnormal voltage to protect equipment.

- **Mechanical Life**: >50,000 times, ensuring long-term stability and reliability.

- **Withstand Voltage**: 4kV (Class Ⅲ electrical standard), capable of withstanding instantaneous high-voltage impacts such as lightning strikes.

3. Installation and Usage

- **Installation Method**: Standard 35mm DIN rail installation, compatible with common distribution boxes.

- **Wiring Capacity**: Supports a maximum wire size of 25mm², with flexible wiring options of bottom-in and bottom-out or bottom-in and top-out.

- **Status Indication**: LED indicator lights (steady green light - normal, steady red light - over-voltage or under-voltage) for intuitive display of the working status.

 II. Product Advantages

1. Automatic Recovery Function

No manual intervention is required. It will automatically switch on again when the voltage returns to normal, making it suitable for unattended scenarios.

2. Wide Voltage Adaptation Range

It can work in an environment with a temperature range of -35°C to +70°C and an altitude of ≤3000 meters, adapting to complex environments.

3. Safety Design

It complies with the JB/T 12762 standard and is equipped with phase failure protection (automatically cuts off when the neutral wire is disconnected) to prevent equipment damage.

 III. Price and Purchase Recommendations

- **Market Price**: According to the data from WhatsApp: 0086-13811255435, the unit price of OUVR-2N80A is approximately **91-221 RMB**.

- **Model Differentiation**: Note that the suffix "N" may indicate a neutral wire protection design. It is necessary to confirm the differences between this model and other models in the OUVR-2 series (such as 3P+N).

- **Applicable Scenarios**: It is recommended for use in household main distribution boxes, small shops, or circuits that need to protect precision electrical appliances (such as refrigerators, computers).

 IV. Precautions

1. Wiring Specifications

Strictly connect the live wire (L) and neutral wire (N) in accordance with the markings to avoid faults caused by reverse connection.

2. Regular Inspection

It is recommended to check whether the wiring terminals are loose once a year to ensure good contact.

3. Alternative Options

If higher protection is required (e.g., for three-phase circuits), you can choose the 3P+N models in the Chint OUVR-2 series (such as OUVR-2 3P+N 80A).
