Over And Under Voltage Protector Factory

Applications and Features:
The CHGQ self-resetting overvoltage and undervoltage protector is designed for use in applications with single-phase AC voltages of 220V/380V, a frequency of 50Hz, and a rated operating current of 100A or less. It is primarily used in electrical circuits in offices, residences, and similar buildings. It quickly and reliably cuts off power during high-voltage surges and undervoltage events, protecting household appliances. It automatically restores power when the voltage returns to normal.

1. Precise over- and under-voltage protection for comprehensive electrical safety: automatically trips and cuts off the circuit during over-voltage, under-voltage, or voltage fluctuations; supports customizable protection thresholds to suit different regional power grid characteristics and sensitive equipment requirements.
2. Tuya Smart Connectivity for remote control of electricity usage: monitor remotely via the Tuya Smart App, with multi-user shared management.
3. Tuya ecosystem integration to expand smart scenarios.
4. Data statistics and fault tracing.
5. Easy installation with strong adaptability.

The intelligent leakage circuit breaker with overload protection (intelligent RCBO / intelligent residual current circuit breaker) is a new generation of electrical safety device that integrates residual current protection, overload protection, short-circuit protection, and IoT smart technology. It is an upgraded version of the intelligent residual current circuit breaker (RCBO). Building on the traditional leakage circuit breaker’s "personal electric shock protection + circuit overload/short-circuit protection," it incorporates WiFi, Bluetooth, 4G, and other communication technologies to achieve remote monitoring, intelligent alerts, and linkage control, specifically designed for electrical safety in homes, commercial buildings, and industrial sites.

The dual-display over-voltage and under-voltage protector is an electrical safety device that integrates dual-screen visual display with precise voltage protection, designed specifically for small to medium electrical applications such as homes and shops. It simultaneously presents two types of key electrical parameters (such as real-time voltage + device status, or incoming voltage + load voltage) through dual display modules (LED digital tube / LCD screen). In addition to the traditional over-voltage and under-voltage protection functions, it also adds visual monitoring features.

The three-display overvoltage and undervoltage protector is an upgraded electrical safety device that integrates triple parameter display with comprehensive voltage protection, suitable for scenarios with higher power monitoring requirements (such as small computer rooms, precision equipment rooms, and commercial shops). Through three screens or a three-in-one display module, it simultaneously shows three key parameters: voltage, current, and power/frequency/status. In addition to overvoltage and undervoltage protection, it also adds load current and power monitoring functions.
