Automatic Voltage Protector – 230V 3680W Surge Protection Relay Socket with 5-Min Delay EU Plug for Refrigerator & AC

Protect valuable appliances from unexpected voltage fluctuations and enjoy greater peace of mind every day. This automatic protection socket monitors incoming power and disconnects the electrical output when voltage moves outside its safe operating range. A built-in delay helps prevent immediate restart after voltage returns to normal, making it especially useful for refrigerators and air conditioners. Designed as a practical voltage protector with dependable surge protection, it combines automatic monitoring and convenient plug-in operation. Clear indicator lights make it easy to see the current operating or protection status at a glance.
