What is the German term for 'blown' in the context of electrical failure?

The correct term for 'blown' in the context of electrical failure is 'Durchgebrannt.' This term is commonly used to describe a situation where a fuse or circuit breaker has failed due to an overload or short circuit, resulting in a discontinuity in the electrical circuit. In electrical terminology, when a fuse 'blows,' it means that it has melted or opened due to excessive current, preventing further current flow and protecting the circuit from damage.

Other terms provided do not apply to the context of electrical failure. 'Entlüften' translates to 'venting' and relates more to releasing air or gas from a system, particularly in plumbing or HVAC contexts. 'Flaschenzug' refers to a 'pulley,' which is a mechanical device unrelated to electrical terminology. 'Ineffizient' means 'inefficient,' generally describing a lack of effectiveness or performance but does not pertain to any specific electrical failure. Thus, 'Durchgebrannt' accurately captures the intended meaning associated with a blown fuse or circuit in the electrical domain.
