摘要： PROBLEM TO BE SOLVED: To provide a power circuit breaker of a simple structure.
SOLUTION: Two contact elements 3 and 4 are housed in a housing 2. These contact elements 3 and 4 form an intermediate space in a closing position and are bridged by a fusible contact element 14. A gas generator 15, arranged opposed to the fusible contact element 14 generates an arc-extinguishing gas at starting. When the fusible contact element 14 is heated to its melting point at the occurrence of a failure current, the fusible contact element 14 is fused. The contact elements 3 and 4 are moved toward an interrupting position by the arc generated between the contact elements 3 and 4. Accordingly, this power circuit breaker 1 can be realized, without additional drive parts for the contact elements 3 and 4. The arc is extinguished in the next zero passing of current by blowing of the arc-extinguishing gas. This arc-extinguishing gas is generated by the gas generator 15 started in the fusing of the fusible contact element 14.
