Latest Patents
One of Hirsbrunner's latest inventions is a miniature circuit breaker designed with improved longevity. This innovative circuit breaker device features a chamber that houses a single break contact system. The system utilizes low contact resistance material mounted on movable and stationary supports arranged in a loop configuration. This design directs arcs between the contacts through an arc chute into a remote portion of the chamber. A push-button is connected through a kinematic linkage that transfers motion with minimal frictional engagement to a movable contact. This mechanism allows the movable contact to engage and disengage with a stationary contact while latching the contacts during normal operation. Additionally, a cantilevered current-carrying bimetal transfers motion caused by I²R heating to an ambient compensating bimetal connected to the latch mechanism. The kinematic linkage includes a latch surface that engages a rollable cylindrical reaction surface of the latch mechanism, facilitating the engagement of the movable contact upon depression of the push-button. In the event of an overload, the latch mechanism is displaced, allowing return springs to separate the contacts and return the push-button to its unactuated position.
