Latest Patents

One of McClellan's latest patents is titled "Cam Following Bridge Contact Carrier for a Current Limiting Circuit." This invention provides a current limiting circuit breaker that features a stationary contact assembly and a movable contact bridge. The contact carrier is designed to connect to the contact bridge and biases it toward the closed position. Notably, the downward biasing force on the contact bridge is mechanically reduced in response to a preselected amount of opening movement of the contact bridge.

Another significant patent is "Current Limiting Circuit Breaker Stationary Contact Assembly." This invention includes a curved input arm with a contact fastened to it and a generally straight output arm that also has a contact. The output arm features an opening for receiving the contact end of the input arm. The contacts are encapsulated in insulating material, which separates the contact arms. Additionally, a magnetic element is embedded in the encapsulation material, creating a field that draws in an armature to reduce the opening force of the contacts as current flows through them.
