    • What is an RCD socket and how does it work?
      2024-04-25
      RCD sockets, or safety sockets with earth leakage protection, prevent electric shock accidents by cutting power in case of leakage or overload. They use leakage protection switches and overload protectors to ensure safety. Equipped with anti-arc function, they supplement but don't replace safe appliance usage. CHNT offers various types including 1-gang and double sockets with different current ratings.
