Single-Phase Intelligent 63A Overvoltage Protection, Adjustable 230VAC

【Protection Device】: The overvoltage and undervoltage protection devices are manufactured using professional production lines and are safe to operate. 【Automatic Recovery】: When the circuit experiences overvoltage, undervoltage, or overcurrent, the voltage protector can instantly cut off the power to protect electrical equipment from damage. When the line voltage returns to normal, the protector automatically resets without requiring manual intervention. 【Overload Protection】: After the overcurrent exceeds 5 times within the specified time, the protector will not automatically restore power. It is necessary to manually press "SET" to reset the power. This effectively protects against frequent switching on and off caused by overcurrent that is not released in time, preventing damage to equipment. 【Reliable Material】: The current-resistant protective casing is made of high-quality material, offering high-temperature resistance, insulation protection, very low power consumption, and a long mechanical lifespan. Do not touch live parts after powering on to avoid electric shock. 【Scope of Application】: The voltage stabilizer is suitable for users or loads with a single-phase AC voltage of 230V, 50/60Hz and a rated working current of 63A or less. It is primarily used for overvoltage, undervoltage, or overcurrent protection of distribution lines in residential distribution boxes, or for protecting single-phase electrical equipment. Tips: 1. The phase conductor must comply with the relevant standard current rating, and the load current must not exceed the maximum protection current rating of the protective device. 2. The neutral wire (N) must be properly connected and secure. The neutral wire (N) of this protection device is directly connected and does not have a disconnecting function. 3. After switching on the product, do not touch live parts to avoid electric shock. 4. This protection device does not have insulation or short-circuit protection. Please use a small circuit breaker at the front for insulation and short-circuit protection. Please disconnect the front circuit breaker when repairing the circuit. If the circuit breaker is not used, the short-circuit current cannot be interrupted in the event of a short circuit fault at the input or output of the circuit breaker. 5. Because the protector has a self-reset function, after overcurrent protection is activated and the protector is disconnected, immediately remove the electrical load and check the circuit. Otherwise, the protector will frequently turn on the electrical load, which, due to prolonged frequent on/off cycles, can damage the electrical device and the protection itself. 6. Please note! If the undervoltage interruption time is greater than 0.3 seconds, the protection will not open after the power failure. (The MCU power failure will not function after a 0.3-second power failure.) 7. After the overcurrent exceeds 5 times within the specified time, the protection lock will not automatically restore power. You must manually press "SET" to unlock the power. This can effectively protect against frequent opening and closing caused by failure to release the overcurrent in time, which can damage the device.
