Title: The Innovative Contributions of Stephen D Cella
Introduction
Stephen D Cella is a notable inventor based in Stone Mountain, GA (US). He has made significant contributions to the field of circuit breaker technology, holding a total of 9 patents. His work focuses on enhancing the functionality and reliability of electrical systems.
Latest Patents
One of Cella's latest patents is the "Thermal sensing bi-metal trip actuator for a circuit breaker." This invention features an actuator designed to initiate a trip of a circuit breaker. The actuator allows load current to pass through a conductor, which is electrically coupled to a contact arm. A thermally responsive bi-metal is integrated into the design, which warps as thermal energy increases, ultimately triggering the circuit breaker to switch from a circuit-making to a circuit-breaking condition.
Another significant patent is the "Circuit breaker with improved trip mechanism." This mechanism includes a contact arm that forms part of an interruptable load current path. It utilizes a spring-loaded, over-center operating mechanism that enhances the efficiency of the circuit breaker. The design ensures that the force exerted by the swinging contact arm maximizes the effectiveness of the toggle mechanism, improving the overall performance of the circuit breaker.
