A controllable trip device includes a magnetic actuator, including a coupling member intended to be coupled to a switching mechanism of an electrical circuit breaker to cause the switching thereof and a coil configured to displace the coupling member towards a tripped position when it is supplied with a pulse of a current of intensity greater than a first predefined threshold for a duration greater than or equal to a predefined duration, a control device, configured to supply the coil, immediately on receipt of a control signal, with a series of pulses of duration equal to the predefined duration and of intensity greater than or equal to the first threshold and less than or equal to a second threshold equal at most to 120% of the first threshold.

A electrical distribution system has been developed to provide a remote central control point for individual circuits, and methods have been developed for retrofitting it to existing service panels or installing it into new service panels. This system provides a power circuit monitoring and control system that fits inside standard residential service panels, both new and retrofitted panels. The entire system can be retrofitted into existing breaker panel systems without the need of removing any permanent structure such as a wall. During this retrofit process, the panel cover on the existing distribution panel is first removed after the power to it is disconnected. The old breaker assembly is removed from the panel, and a circuit controller is then installed in the now available space within the panel. A new service panel enclosure with a circuit breaker assembly is installed directly over top of the enclosure.

This disclosure relates to various embodiments of lockout relay devices. In one embodiment, a lockout relay device may transition between a closed position and a lockout position in response to an action of a deck device. The lockout relay may further be configured to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation. A manual actuator may permit a manual transition of the lockout relay device from the closed position to the lockout position and from the lockout position to the closed position. The lockout relay device may remain in the lockout position until the occurrence of one of a manual adjustment and a reset operation.

A system includes a first electrically conductive electrode and a second electrically conductive electrode. The system further includes a magnetic field source. The system also includes a magnetic shape memory (MSM) alloy positioned within a magnetic field of the magnetic field source with a portion of the MSM alloy being coupled with the first electrically conductive electrode. The magnetic field causes the MSM alloy to bend to contact the second electrically conductive electrode when the MSM alloy is in a first state. The magnetic field has no or negligible effect on the MSM alloy when the MSM alloy is in a second state.

A ground fault circuit interrupter device includes a switch unit for controlling a power connection between input and output ends; a leakage protection unit including a leakage detection module, for generating a leakage fault signal upon detecting a leakage current signal, and a leakage drive module including a first coil, for driving the switch unit to disconnect the power connection in response to the leakage fault signal; a timing unit including a timing control module, for performing timing in response to a time duration setting signal and generating a timed trip signal after a first preset time duration elapses, a time duration setting module for sending the time duration setting signal to the timing control module, and a timing drive module including a second coil separate from the first coil, for driving the switch unit to disconnect the power connection in response to the timed trip signal.
