Definitions

  • Residual current circuit breakers are widely used today and are used to deenergize consumer systems when fault currents occur on the electrical conductors.
  • FIG. 4 serves for a more detailed explanation of the flying bearing 31 of the movable contact pieces 36, which are guided in a switching shaft 35 which can be pivoted about a pivot point 26 under the action of the toggle lever 32 acting in the swivel joint 29.
  • the flying bearing 31 is formed from two opposite tips, between which the movable contact 36 is arranged.
  • the lower part of the movable contact 36 belongs to the contact point 40; the upper part of the movable contact 36 is acted upon by a spring 33.
  • the spring 33 is tensioned, i. H. a force acts on the upper lever arm of the movable contact 36, which ensures that the lower part of the movable contact is pressed against the fixed contact 37 due to the support in the fly bearing 31.
  • the contact arrangement shown in this illustration consists of a movable contact 36, which is guided in a switching shaft 35 and is equipped with a contact piece 38 made of arc-resistant material, and a fixed contact 37, which leads via a conductor rail 43 to the connecting terminal 42 and on it free end also has a contact piece 39 made of arc-resistant material.
  • a switch toggle 58 serving as a manual actuating member 58 is arranged on the top of the housing 51 next to the test button 49 and engages with the switching mechanism hidden by the triggering unit 56 in this view.
  • the only feature of the rear derailleur is the lower part of the toggle lever 32, which is connected to the selector shaft 35.
  • the equipment of the control shaft 35, in which the movable contact 36 is guided in a floating bearing 31, with the control cam 47 also helps to reduce the manufacturing costs, because this means that the load resistor switched into the test circuit, which would otherwise be required, is dimensioned to make it permanently current-proof to make, can be omitted, since the closing of the test circuit is prevented by the switching cam 47 when the residual current circuit breaker is switched off.
