  • Inertial catch for an automatic transfer switch power contractor
    Patent number: 8138861
    Abstract: A catch assembly coupled to the operating mechanism of the ATS is provided. The catch assembly is structured to arrest movement within the operating mechanism when the operating mechanism moves at more than the speed for which it was designed. That is, the catch assembly does not engage when the operating mechanism is stationary, or moving at a standard speed, i.e. the speed at which the operating mechanism was intended to move. When there is a strong over-current, such as during a withstand test, a magnetic field causes a movable contact to separate from a fixed contact assembly which, in turn, causes the operating mechanism to move at a speed that is faster than the standard speed. The catch assembly is structured to engage and arrest the motion of the operating mechanism when the operating mechanism moves at a speed that is faster than the standard speed.
