Definitions

  • the invention relates to a switching device with housing, in particular circuit breaker, in which at least one terminal is arranged in a receptacle formed in the housing, wherein the receptacle is at least partially closed at the front by a cover, and in the front cover terminal openings are formed for the terminals, wherein two plate-shaped or rib-shaped shielding elements are formed integrally on the housing on both sides of the clamping openings, so that between two adjacent terminal openings at least two separate shielding elements are provided, which form a free gap between the two Abschim instituten, and wherein the housing clamping screw holes are formed for the terminals.
  • Such switching devices are used as a circuit breaker, in particular circuit breaker, in a variety of applications in use.
  • Electrical switching devices must comply with specified safety regulations.
  • the dense use of electrical switching devices such as in control boxes makes special security features necessary for such switching devices.
  • Regulations such as the US UL 489 specify minimum distances between the externally accessible current-carrying conductors of neighboring electrical switching devices. For example, for switching devices up to an operating voltage of U N less than or equal to 300 V, an air gap of at least 19.1 mm between two adjacent live conductors is prescribed. At an operating voltage of U N > 300 V, the prescribed minimum air gap between two adjacent live conductors is already 25.4 mm.
  • the leakage current path typically corresponds to the air flow path. Therefore, switching devices to meet the required minimum leakage current path are usually larger than the air flow path would require. The use in the low voltage range of conventional, narrow designs for switching devices from a certain operating voltage is therefore not possible.

  • the shielding elements are arranged offset parallel to a housing outside and at a distance from the housing outside to the inside, so that when two switching devices arranged next to each other two shielding elements next to each other form a free gap.
  • the path of the leakage current occurring is juxtaposed with juxtaposed similar switching devices, since the shielding of two adjacent, similar switching devices are not superimposed and results in a significantly extended creepage distance by the distance between the shielding and the gap formed thereby.
