IPC: H01H73/50
Filed: 2002-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a main contact from being forced to open accidentally due to an inrush current which occurs at a load starting.  <P>SOLUTION: When a cord short circuit current, etc., runs through a bimetal 45, because of electromagnetic force between a second iron core 60 and a first iron core 61, the second core 60 moves toward the first core 61 against force of a spring 64 until a side piece 60a comes into contact with an end surface of a concave groove 31h and reaches a target position P2. The electromagnetic force additionally attracts and vibrates the first core 61 toward the second core 60 and rotates a first tripping plate 41. Since the instantaneous inrush current occurs in very short time at a start-up of a motor or an invertor, it stops before the moving second core 60 reaches a target position P2. Then the distance between the first core 61 and the second core 60 is kept above a predetermined value and the main contact is prevented from being forced to open accidentally.  <P>COPYRIGHT: (C)2004,JPO
