Vacuum Circuit Breaker

The vacuum circuit breaker is commonly known as the frame-type circuit breaker. Its main function is to cut off a large current. Its working principle is pure mechanical deformation causing micro switch to act. When the pressure increases, the pressure sensing components, such as diaphragm, bellows, and piston, are deformed. They will move upwards, pass through railing spring and other mechanical structures, and finally start the top micro switch to output electric signal. The setting modes of mechanical pressure switch are all continuous displacement type from the function aspect. A single point can be set and at most three different set points can be reached.
