When any of these events occur, the socket automatically cuts power to prevent appliance damage.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the socket reconnect power automatically after a fault?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Once the voltage or current returns to within the normal range, the socket will automatically restore power after the user-defined delay time (1–500 seconds). This delay is adjustable, giving you full control over how quickly reconnection occurs.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this socket with all my 220V–240V home appliances?\u003c\/h4\u003e\n\u003cp\u003eA: This socket is compatible with standard 220V–240V, 50\/60Hz circuits and supports up to 16A load current. It is suitable for most common household appliances such as refrigerators, washing machines, air conditioners, and televisions. Always ensure your appliance's rated current does not exceed the socket's 16A maximum load.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I adjust the voltage and current protection thresholds?\u003c\/h4\u003e\n\u003cp\u003eA: The overvoltage, undervoltage, and overcurrent thresholds are all user-adjustable directly on the device via its control buttons. The large LED display makes it easy to see the values as you configure them. No additional tools or electrician expertise are required for setup.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does this metering protector socket protect against?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This socket protects your connected appliances from three common electrical hazards: overvoltage (voltage exceeding your set threshold, up to 300V), undervoltage (voltage dropping below your set threshold, as low as 140V), and overcurrent (current exceeding the 1–16A adjustable limit).
