    Abstract: An electrical protection device of circuit-breaker type including a casing, a severing system, positioned in the casing, configured to assume inactivated and activated states corresponding to the on and off states of the electrical protection device, respectively, and a connection system configured to assume an open state in which it allows the electrical cable to be inserted and a second, closed state in which it surrounds the electrical cable. The connection system and the severing system are configured and arranged such that, when the connection system is in the closed state, the severing system severs the electrical cable when passing from the inactivated state to the activated state.

    Abstract: A multi-level feedback actuator assembly for a circuit breaker assembly includes a rotary solenoid, an electric actuator assembly and a manual actuator assembly. The electric actuator assembly includes a switch assembly with an actuator. The manual actuator assembly includes a number of primary actuators, a linkage assembly, and a cam assembly. The number of primary actuators includes a first actuator with a body. The first actuator body is structured to move over a path having at least a first portion and a second portion. The rotary solenoid is operatively coupled to the linkage assembly. The linkage assembly is further operatively coupled to an operating mechanism crossbar. In this configuration, the linkage assembly is structured to apply at least a first bias and a second bias to the first actuator body. Further, the first bias is noticeably different from said second bias.

    Abstract: A low-voltage circuit breaker includes at least one fixed contact, for each pole, which is electrically connected to a terminal for connection to an electric circuit, and a corresponding moving contact which is associable/separable with respect to the fixed contact by a rotation of the moving contact. The low-voltage circuit breaker further includes an arc chamber positioned in correspondence of the fixed contact, and a rotating contact supporting shaft common to all poles, which is functionally connected to an actuation mechanism of the circuit breaker, where the actuation mechanism includes a kinematic system operatively connected to an actuation lever for opening/closing operations and provided with opening springs and a tripping shaft for releasing the kinematic system and allowing its movement from a closed to an open position. The low-voltage circuit breaker further includes, for each pole, a quick acting trip device.

    Abstract: Embodiments of the present disclosure relate to a switch device, comprising: a first three-position switch; a second three-position switch disposed below the first three-position switch; a circuit breaker disposed between the first three-position switch and the second three-position switch. A first interlock unit is disposed above the circuit breaker and connected to the circuit breaker and the first three-position switch, and configured to block a manual operation of the first three-position switch in a closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the first three-position switch is manually operated in an open state of the circuit breaker. A second interlock unit is disposed below the circuit breaker and connected to the circuit breaker and the second three-position switch, and is configured to block a manual operation of the second three-position switch in the closed state of the circuit breaker, and configured to block a manual closing operation of the circuit breaker while the second three-position switch is manually operated in the open state of the circuit breaker.

    Abstract: A circuit interrupter includes a handle, an operating linkage, and a spring that are situated on a housing, with the spring extending between the handle and the operating linkage. The circuit interrupter is movable among an ON position, an OFF position, and a TRIP position, and the operating linkage includes a contact arm that is pivotable with respect to the housing to move a movable contact between an OPEN position and a CLOSED position with respect to a stationary contact. The handle has a toggle point, and when the spring is situated at a first side of the toggle point, the spring biases the contact arm to the ON position. When the spring is situated at a second side of the toggle point, the spring biases the contact arm to the OFF position or the TRIP position.
