Summary:A fusion welding isolation mechanism for an operating mechanism of a circuit breaker is provided. The operating mechanism of circuit breaker includes: a tripping component, a left side, a right side plate, a latch, a half shaft, a lever, and a main shaft. The tripping component, the latch, and the lever are mounted between the left side plate and the right side plate. The half shaft and the main shaft penetrate through the left side plate and the right side plate, and extend out of the left side plate and the right side plate. The tripping component, the latch, the half shaft, the lever, and the main shaft move in linkage. The lever and the main shaft are provided with isolation devices for preventing an operation handle from an opening operation when a moving contact is subject to fusion welding.
