Definitions

  • the invention relates to the technical field of a protective switching device for a low-voltage circuit with an electronic interruption unit and a method for a protective switching device for a low-voltage circuit with an electronic interruption unit.
  • Low voltage refers to voltages of up to 1000 volts AC or up to 1500 volts DC. Low voltage refers in particular to voltages greater than extra-low voltage, with values of 50 volts AC or 120 volts DC.
  • Low-voltage circuits, networks, or systems refer to circuits with nominal or rated currents of up to 125 amps, more specifically up to 63 amps.
  • Low-voltage circuits specifically refer to circuits with nominal or rated currents of up to 50 amps, 40 amps, 32 amps, 25 amps, 16 amps, or 10 amps.
  • the current values mentioned refer specifically to nominal, rated, and/or breaking currents, i.e., the maximum current that is normally conducted through the circuit or at which the electrical circuit is usually interrupted, for example, by a protective device such as a protective switching device, miniature circuit breaker, or circuit breaker.
  • the rated currents can be further staggered, from 0.5 A to 1 A, 2 A, 3 A, 4 A, 5 A, 6 A, 7 A, 8 A, 9 A, 10 A, etc. up to 16 A.
  • Miniature circuit breakers are long-established overcurrent protection devices used in low-voltage electrical circuits. They protect cables from damage caused by overheating due to excessive current and/or short circuits.
  • a miniature circuit breaker can automatically switch off the circuit in the event of an overload and/or short circuit.
  • a circuit breaker is a non-self-resetting safety device.
  • circuit breakers are designed for currents greater than 125 A, and in some cases even as low as 63 A. Miniature circuit breakers are therefore simpler and more delicate in design. Miniature circuit breakers typically have a mounting option for mounting on a so-called top-hat rail (DIN rail, TH35).
  • Miniature circuit breakers are electromechanically constructed. They contain a mechanical switching contact or shunt release within a housing to interrupt (trip) the electrical current.
  • a bimetallic protective element or bimetallic element is used to trip (interrupt) the circuit in the event of a prolonged overcurrent (overcurrent protection) or thermal overload (overload protection).

  • One or more arc-quenching chambers or arc-quenching devices are provided.
  • connection elements for conductors of the electrical circuit to be protected are used.
  • Circuit breakers with an electronic interruption unit are relatively new developments. They feature a semiconductor-based electronic interruption unit. This means that the electrical current flow of the low-voltage circuit is guided via semiconductor components or semiconductor switches, which interrupt the electrical current flow or can be switched to conduction. Circuit breakers with an electronic interruption unit also often feature a mechanical isolating contact system, in particular with isolating properties in accordance with the relevant standards for low-voltage circuits, whereby the contacts of the mechanical isolating contact system are connected in series to the electronic interruption unit, i.e. the current of the low-voltage circuit to be protected is conducted via both the mechanical isolating contact system and the electronic interruption unit.
