CURRENT BREAKER
Document Type and Number:
Japanese Patent JP2021061146
Kind Code:
A
Abstract:
To suppress arc generation.SOLUTION: A current breaker 1 comprises a drive mechanism 7, a first terminal 211, a second terminal 221, a separation part 23, a housing 9, an operation pin 8, and a conductive part 4. The separation part 23 connects between the first terminal 211 and the second terminal 221. The operation pin 8 is provided inside the housing 9. When the operation pin 8 moves by being driven by the drive mechanism 7, it separates the separation part 23 from at least one of the first terminal 211 and the second terminal 221. The conductive part 4 is disposed between a rear end of the operation pin 8 and the separation part 23 in the movement direction of the operation pin 8. The conductive part 4 moves in conjunction with the operation pin 8. The conductive part 4 brings the first terminal 211 and the second terminal 221, separated from each other, into conduction with each other. The conductive part 4 has a fusion part which fuses if a current having a value equal to or higher than an allowable value flows thereto.SELECTED DRAWING: Figure 1
