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.
- Core Parameters and Functions1. 電気 仕様
定格電圧: 230V AC (single-phase), with a frequency of 50Hz.
定格電流: 80あ, suitable for circuit protection of high-power loads (such as air conditioners, water heaters, 等).
極数: 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.
- Response and Durability
Operating Time: ≤1 second, which can quickly cut off abnormal voltage to protect equipment.
Mechanical Life: >50,000 回, ensuring long-term stability and reliability.
Withstand Voltage: 4kV (Class Ⅲ electrical standard), capable of withstanding instantaneous high-voltage impacts such as lightning strikes.
- Installation and Usage
設置方法: 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.
- Product Advantages
- 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.
- 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.
- 安全設計
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
市場価格: According to the data from WhatsApp: 0086-13811255435, the unit price of OUVR-2N80A is approximately 91-221 人民元.
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).
該当するシナリオ: 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).
- 予防
- Wiring Specifications
Strictly connect the live wire (L) and neutral wire (N) in accordance with the markings to avoid faults caused by reverse connection.
- Regular Inspection
It is recommended to check whether the wiring terminals are loose once a year to ensure good contact.
- Alternative Options
If higher protection is required (例えば, for three-phase circuits), you can choose the 3P+N models in the Chint OUVR-2 series (such as OUVR-2 3P+N 80A).
