摘要： In one embodiment, an energy management module having a form factor adapted to fit within one or more slots of a load center or panelboard of a structure is provided. The energy management module includes a housing configured to fit within the one or more slots of the load center or panelboard. It has a plurality of current sensor connectors configured to connect to current sensors that measure current flowing through breakers of the load center or panelboard to circuits within the structure. One or more power measurement DSPs are provided to measure power consumption of the circuits. It further has a microcontroller unit with a wireless network interface configured to communicate the power consumption measurements to a host controller or cloud services that provide the power consumption measurements for display in an energy management user interface.

摘要： An integrated power protection and conditioning system is disclosed. The integrated power protection and conditioning system includes a variable frequency drive (VFD) having a VFD housing and a power conversion circuit contained within the VFD housing and operable to provide a controlled output power to a load. The integrated power protection and conditioning system also includes a branch protection device having a branch protection housing and a power protection circuit contained within the outer housing and operable to selectively interrupt current flow from a power source to the VFD during a fault condition. The branch protection device is coupled to the VFD, such that the branch protection device is integrated with the VFD.

摘要： An electrical panel board includes an enclosure defining a first and second chamber, a power distribution module disposed in one of the first chamber and the second chamber and adapted to electrically connect a main power source to receive power thereof with one or more loads. A neutral assembly is positioned in the remaining of the first chamber and the second chamber and securable to the rear wall of the enclosure. The neutral assembly includes a neutral circuit and a ground fault protection unit electrically coupled to each other. The neutral assembly having the neutral circuit and the ground fault protection unit extends from the rear wall to an imaginary plane which is off set rearwardly from an imaginary plane along which the power distribution module extends from the rear wall.

摘要： Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

摘要： An apparatus includes a cell pan that supports a circuit breaker within a switchgear cell, and a lift pan that carries a circuit breaker outside of the switchgear cell. The lift pan has a track for a roller on the circuit breaker. The apparatus further includes an extension rail that interconnects the lift pan with the cell pan in an aligned position. With the lift pan in aligned position, the track on the lift pan can receive the roller upon horizontal draw-out movement of the circuit breaker from the cell pan. A latch on the extension rail has a blocking position in which it blocks the roller from rolling outward off the cell pan, and has a non-blocking position in which it does not block the roller from rolling outward off the cell pan. The latch automatically moves from the blocking position to the non-blocking position under the influence of the lift pan upon movement of the lift pan into the aligned position.
