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

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