Title:
CIRCUIT BREAKING DEVICE
Document Type and Number:
Japanese Patent JP3886735
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a small, inexpensive circuit breaking device preventing the fusion loss of a terminal caused by arc discharge without using two relay switches and a control circuit of them.
SOLUTION: A load side terminal 12 connected to a load part, a power source side terminal 13 connected to a power source part, and a consumable electrode 14 connected to the power source side terminal 13 are fixed to a circuit body 2, a moving plug 3 is movably installed in the device body 2, and in a process of moving a current carrying part 41 of the moving plug 3 from a circuit opening position to a circuit closing position, the current carrying part 41 first comes in contact with the load side terminal 12, next comes in contact with the consumable electrode 14 in a state connected to the load side terminal 12, finally comes in contact with the power source side terminal 13 in a state connected to the load side terminal 12 and the consumable electrode 14 by shifting the arrangement of them. The consumable electrode 14 is composed of a consumable electrode with resistance 35 connected to the power source side terminal 13 through a resistance 39 and a through consumable electrode 36 directly connected to the power source side terminal not through the resistance.
