Definitions

  • the invention relates to a self-releasing circuit breaker for short-circuit currents.
  • Short circuits can be caused, for example, by faulty isolation or by a switching error in electrical systems. Such short-circuit currents can be detected by protective devices and the current-carrying conductors are switched off by circuit breakers or by fuse. Short circuits can have different causes. Often short circuits are caused by a broken insulation or by insulation changes. Faulty circuits in electrical switchgear and devices as well as non-compliance with safety regulations can lead to short-circuits. Failure to limit a short-circuit current can cause overheating in the line or electrical components. To prevent the consequences of electrical short circuits, for example, in low-voltage networks circuit breakers and fuses can be used.
