To reduce cost, the disclosed circuits utilize a simple DC capacitor without any additional power conditioning switches or converters. In one exemplary embodiment, the disclosed circuits are embedded inside a power line cord to provide a ride-through during the brief interval of time such power line disturbances occur.

The elastic member is soldered onto the second conductor layers and the current-carrying electrode terminals in a state that the elastic member maintains a level of stress allowing at least one of the current-carrying electrode terminals among the second conductor layers and the current-carrying electrode terminals to be separated from the elastic member by deformation of the solder even in a case where the solder is not completely melted.
192 Shortage voltage trip device of molded case circuit breaker US13726373 2012-12-24 US08749328B2 2014-06-10 Seung Jin Ham
Provided is a shortage voltage trip device of a molded case circuit breaker. In the molded case circuit breaker, driving current applied into a trip driving part is reduced in proportion to reduction of a power applied into a circuit. When the voltage applied into the circuit is greater than a rated voltage, the trip driving part is stopped, and an operation of a trip driving mechanism is restricted by a trip lever. When the voltage applied into the circuit is less than the rated voltage, the trip driving part is operated, and the restriction of the trip driving mechanism is released by the trip lever rotated by being linked with the operation of the trip driving part. Thus, the circuit may be more simply switched, and operation reliability of a product may be improved. Also, the product may have a more simplified structure.
