Nowadays, the plastic case circuit breaker it is widely used and well known to most people. Plastic circuit breaker can automatically cut off the current after the current exceeds the tripping setting. How does the splitting of plastic case circuit breaker work? Let's take a look at the process of splitting the gate of intelligent plastic circuit breakers today!

Plastic case circuit breaker manufacturer said the process of splitting the door of the plastic case circuit breaker is when the operating mechanism receives the command to split the door, the top bar of the splitting core moves to remove the closing maintenance device. Under the action of the energy release of the parting spring and the closing buffer spring, the large shaft is driven to rotate, driving the pressure rod, rotating shaft and other links, driving the conductive voltage rod to move down the brake. When the splitting is near the end, the splitting oil damper at the end of the conductive rod begins to damp, and the speed of the conductive rod gradually becomes slower. Finally, the leakage circuit breaker in order to trip the spring preload, the roller on the elbow joint arm of the large shaft trips, so that it is against the buffer of the block, keeping the breaker in the final tripping position.
