Abstract

Circuit-breaker come with either a front connect or a rear connect point. Depending on which circuit-breaker will be installed at an installation, the rack mount and wiring is designed accordingly. This might cause problems to customers at one point or the other due to fact that the connection points are provided either in the front or the rear of the circuit-breakers. The customers may not have the flexibility to choose a circuit-breaker and may have to either buy circuit-breakers which fit the wiring design. From a utility perspective, there are connection plates or connection kits which may be used along with either the front or rear connection point circuit-breakers. However the invention eliminates the need for additional parts. The invention provides a connection point agnostic way of installing a circuit-breaker.

ADAPTABLE CIRCUIT‐BREAKER FOR FRONT OR REAR CONNECTION POINT   

BACKGROUND  

 

The electrical power system is a power network with a large number of electrical equipment. The large  number of electrical equipment might cause a power overload on the electrical power system due to  accidental short circuits. At times there might be short circuits introduced by malfunctioning electrical  equipment. During such conditions (short circuit faults or overload conditions), the equipment as well as  the  power  network  may  suffer  high  stress  of  fault  current  in  them  which  may  damage  the  electrical  networks and equipment. To protect the electrical equipment and power networks from fault currents  the fault current should be cleared from the electrical system within no time. Furthermore, once the  fault is cleared, the system must go back to its normal working condition as soon as possible. For timely  protection of the electrical network, proper devices called switching devices or circuit‐breakers may be  used to disconnect (break) and restore the circuit quickly. Not doing so might cause huge damage not  only to the electrical networks and systems connected to the electrical network but also to property and  might cause serious accidents that may be fatal. The circuit‐breakers or switching devices must operate  safely under all fault conditions.  
 
Before circuit breakers were invented, an electrical fuse was used for protection from fault currents.  Under fault conditions, the electrical fuse would blow off thus breaking the electrical circuit. To restore  the electrical circuit, the broken fuse had to be replaced. This is a disadvantage compared to a circuit  breaker where the circuit may be restored without replacing a part. Electrical fuses are used in many  components including home and automotive electrical circuits. They are popular due to their low cost.  However, various types of circuit breakers have been invented and have found their place for different  ratings and applications.  
 
Circuit‐breakers have a fixed contact point and a moving contact point. Under normal conditions, the  two  contact  points  are  in  contact  to  form  a  circuit.  Under  fault  condition,  the  moving  contact  point  breaks away from the fixed contact point thus breaking the circuit and providing protection.  
 
The circuit‐breaker consists of fixed and moving metallic contact points. Under normal conditions, the  fixed and moving contact points are in contact with each other due to a force on the moving contact  point.  The  force  in ...
