Definitions

  • the invention relates to an electromagnetic circuit breaker comprising a main case, a pair of contacts enclosed by said main case, a circuit breaker assembly to move one of the contacts between a closed position and an open position, an electromagnetic main assembly for actuating said circuit breaker assembly upon the occurrence of predetermined electrical conditions and an auxiliary switch responsive to movements of said circuit breaker assembly for indicating whether said contacts are open or closed, wherein the auxiliary switch has switched terminals.
  • Circuit breakers of the electromagnetic type having an auxiliary switch are well-known, for example, one such circuit breaker is shown in EP 1 511 055 A2 .
  • the described circuit breaker comprises a moveable contact, mounted on a moveable arm, and a rigidly mounted stationary contact.
  • An operating handle link is coupled to the moveable arm which is part of the circuit breaker assembly.
  • the circuit breaker assembly comprises a collapsible toggle assembly.
  • the moveable contact is operated between an open position and a closed position through rotation of the operating handle.
  • the circuit breaker further contains an electromagnetic assembly which, in response to predetermined electrical conditions, collapses the toggle assembly to thereby electrically trip "open" the contacts.
  • EP 1 511 055 A2 further provides for an arrangement which indicates the condition of the circuit breaker as being “closed” or "open".
  • the arrangement for indicating the condition of the circuit breaker comprises an auxiliary switch located within a switch case and responsive to the distinctive movements of the circuit breaker linkage mechanism.
  • the switch is located approximately intermediate of main terminals of the circuit breaker with the terminals of the switch extending generally in the same direction as the main terminals. The switch indicates the normal “on” and “off” conditions of the circuit breaker and is therefore mechanically linked to the circuit breaker assembly.
  • the object of the invention is to externally control such an electromagnetic circuit breaker while the circuit breaker has a compact design.
  • an electromagnetic circuit breaker comprising a main case, a pair of contacts enclosed by said main case, a circuit breaker assembly to move one of the contacts between a closed position and an open position, an electromagnetic main assembly for actuating said circuit breaker assembly upon the occurrence of predetermined electrical conditions, and an auxiliary switch responsive to movements of said circuit breaker assembly for indicating whether said contacts are open or closed, wherein the auxiliary switch has switch terminals, wherein a control assembly is provided for actuating said circuit breaker assembly upon an external electrical signal, said control assembly has control terminals, and wherein a switch case is provided carrying said switch terminals and said control terminals and accommodating said auxiliary switch.
  • the electromagnetic circuit breaker comprises a control assembly for actuating said circuit breaker assembly upon an external electrical signal, wherein said control assembly has control terminals.

  • the electromagnetic circuit breaker comprises a switch case carrying both the switch terminals and the control terminals.
  • the circuit breaker cases contain the electromagnetic main assembly, the control assembly as well as the auxiliary switch. Therefore, the electromagnetic circuit breaker according to the invention can be provided in the form of a one-pole circuit breaker having several functions, which are the function of tripping the circuit upon the occurrence of pre-determined electrical conditions such as current overloads and the function of externally controlling the circuit breaker (trip-off) while at the same time providing an external signal via an auxiliary switch (indicating the tripping of the breaker - whether by mechanical, electrical or tripping-from-a-remote-location).
  • auxiliary switch and the control assembly are carried by one single switch case. This also provides for a compact design.
  • Each of the contacts is connected to a main terminal wherein the circuit breaker assembly comprises a main coil connected in series to said terminals.
  • the main coil moves a core by means of an electromagnetic flux in a well-known manner in order to actuate the circuit breaker assembly when predetermined electrical conditions such as a current overload occurs.

  • each of the contacts is connected to main terminal, wherein said main terminals extend substantially in the same direction from the main case.
  • the switch case is located substantially intermediate the main terminals with the switch terminals and the control terminals extending generally in the same direction as the main terminals.
  • the electromagnetic main assembly comprises a main coil about a tube for moving a core of magnetizable material movable in said tube so that the main coil can trip the circuit breaker assembly.
  • the control assembly comprises a control coil which is arranged about said same tube for moving said same core within the tube. This provides for a very compact design of the coils which constitute a single component with two functions.

  • the circuit breaker 1 further comprises a circuit breaker assembly 9 mounted within the main case 4 and having various linkages rotatably supported therein.
  • An actuatable member 10 is moved by an internal actuator 11 attached to the operating handle 5, wherein it is rotatably supported relative to the main case 4.
  • the operating handle 5 also has an external portion 12 protruding through an opening 13 of the main case 4.
  • a movable contact support 14 carrying the movable first contact 2 pivotally supported to rotate about a pin 15.
  • the movable contact support 14 is joined to an linkage mechanism 16 by a pin 17, which allows the movable contact support 14 to be moved down (with respect to Figure 2 ), in order that the movable first contact 2 closes against a fixed second contact 3 as shown in Figure 1 .
  • the fixed second contact 3 is supported on the half-case 6 and is electrically connected to the external line terminal 7.
  • the movable first contact 2 is electrically connected through a conductive circuit to the external load terminal 8.

  • All switch terminals 24, 25, 26 and the auxiliary switch 23 itself are schematically shown in Figure 4 depicting the other side of the circuit breaker 1.
  • the switch case 20 is a separate case from the main case 4.
  • the switch case 20 is accommodated within the switch receptacle 18 and is fixed with protrusions 30 in the recesses 19 of the switch receptacle 18.
  • the terminal cavities 31, 32, 33, 34, 35 are open to a backside of the switch case 20 for receiving counter terminals (not shown), in the present embodiment in the form of female terminals, to be connected to the terminals 24, 25, 26, 27, 28.
  • the terminals 24, 25, 26, 27, 28 are entirely encapsulated within the switch case 20 protected from unintentionally coming into electrical contact with other electrical elements.
  • the mains terminals 7, 8 extend substantially in the same direction from the main case 4.
  • the switch case 20 is located intermediate the main terminals 7, 8 with the terminals 24, 25, 26, 27, 28 extending in the same direction as the main terminals 7, 8. So all electrical terminals of the circuit breaker 1 can be reached form one side of the main case 4.
