Latest Patents

One of Takemura's latest patents is a circuit breaker designed to enhance safety and functionality. This circuit breaker features one or two circuit-breaking electric element blocks, which include current source side and load side terminals, fixed and movable contactors. It incorporates means for forcibly tripping the movable contactor away from the fixed contactor, responding electromagnetically to an overcurrent. Additionally, it includes an arc suppressing means and a mechanical contact operating mechanism that allows for efficient operation within a single housing.

Another significant patent is the multipolar type circuit breaker, which consists of multiple breaker element assemblies corresponding to the number of AC source poles. Each assembly includes a contact operating mechanism for ON and OFF operations of a movable contactor connected to a load side terminal. The trip mechanism forms an electric current path and interlinks with the contact operating mechanism to release its normal ON position latch upon the incoming of excessive current. This innovative design allows for synchronized tripping operations across all assemblies, enhancing the overall safety and reliability of electrical systems.
