Abstract
A circuit breaker includes at least one moveable contact. The moveable electrode is operably connected to a Thomson coil actuator that can separate and open the contacts of the circuit breaker. A sensor senses current or voltage in the circuit breaker. When a condition exists that triggers an opening action, a controller will use select a current level to apply to the Thomson coil actuator. The selected current level will vary based on the sensed current or voltage level. The controller will cause a driver to apply the selected current level to the Thomson coil actuator, and it will cause the contacts to separate and open. If the circuit breaker is a vacuum interrupter, the vacuum interrupter may employ a multi-section bellows in which each section has unique structural characteristics as compared to the other sections, so that different sections will dominate as the Thomson coil's speed of operation varies.
