What is the German term for 'circuit breaker'?

The German term for 'circuit breaker' is "Sicherungsautomat." This term directly refers to a device that automatically interrupts the electrical flow in a circuit when an overload or fault occurs, thereby providing protection against electrical fires and equipment damage. The word itself can be broken down into "Sicherung," meaning "protection," and "Automat," indicating that it operates automatically.

Understanding the terminology is essential for anyone working with electrical systems or safety devices, as using the correct terms ensures clear communication among professionals and in technical documentation. The other terms do not relate to electrical circuit protection devices: "Klammer" refers to a clamp or clip, "Abstand" means distance, and "Kupplung" translates to coupling, none of which pertain to circuit breakers.
