Abstract: A circuit breaker includes a current entry which conducts an electrical current via a wound coil conductor strip of a first coil to a first fixed contact, and includes a contact rocker which can be moved between two switching positions. The contact rocker includes mutually connected contact limbs. A first switching position of the contact rocker, electrically connects the first fixed contact with a second fixed contact which is connected via a wound coil conductor strip of a second coil to a current exit for dissipating an electrical current flowing through the contact limbs of the contact rocker and the coil conductor strips of the coils to a current exit of the circuit breaker. A high electrical current which flows through the wound coil conductor strips of the coils and through the contact limbs of the contact rocker produces a magnetic field which generates a switching force which moves the contact rocker from the first switching position into a second switching position in which the two fixed contacts are electrically separated to interrupt the electrical current.

Abstract: A load center includes a housing, a cover, and a circuit breaker. The load center can be retrofitted to further include a rotational motor, an actuator member, and a guide insert. The rotational motor includes a threaded drive shaft positioned through an aperture formed in the cover. The actuator member is threadingly engaged with the threaded drive shaft. The actuator member is oriented relative to the cover such that a handle of the circuit breaker is positioned through an aperture of the actuating member. Rotation of the threaded drive shaft causes the actuator member to translate such that a first actuating surface of the actuator member engages the handle and switches the handle from an OFF position to an ON position. The handle of the circuit breaker has full range of travel between the ON and OFF positions in response to the actuator member being moved into a neutral position.

Abstract: A cutout is used in an electrical distribution network to electrically connect a first electric cable with a second electrical cable, The cutout includes an electrically non-conductive insulator having first and second end. A first terminal assembly is secured to the first insulator end. A second terminal assembly is secured to the second insulator end. A failsafe fuse assembly is pivotally secured to the second terminal and is movable between an engaged position and a lockout position. A reclosing mechanism is secured to the first terminal and monitors electrical current through the fuse assembly. If a fault condition exists, the reclosing mechanism opens and then closes the electrical link between the first and second electrical cable. If, after a predetermined number of closes, the fault condition still exists, the reclosing mechanism disconnects from the fuse assembly, allowing the fuse assembly to fall to the lockout position.
