摘要： In this method, the voltage outage load-side is an opening of the circuit breaker, and the circuit breaker is able to interrupt the flow of electric current in an electric connection including an electric conductor. The auxiliary unit comprises a current sensor for measuring the intensity of the current flowing in the electric conductor and a first detection means for detecting the voltage outage load-side from the circuit breaker. The method comprises the following steps: measuring the intensity of the current flowing in the electric conductor, detecting the voltage outage load-side from the electric circuit breaker, determining a cause of the detected voltage outage load-side from the circuit breaker, said cause being selected from the group consisting in: an electric overload, a short-circuit and a voltage drop.

摘要： A circuit breaker is referenced that has an indicator lamp that identifies a fault condition after power is interrupted to the circuit breaker. This solution uses light emitting diodes (LEDs) to indicate the trip condition. This solution does not require the power to be enabled to the load side of the circuit breaker in order to power the LEDs to display a trip condition. An overload may be detected when the fault current generates sufficient heat in a strip composed of a resistive element or bimetal to cause the bimetal to deflect and/or bend. The mechanical deflection triggers a trip assembly that includes a spring trip level to force a moveable contact attached to a moveable conductive blade away from a stationary contact, thereby breaking the circuit.

摘要： A power switch including a contact configured to selectively electrically connect a line input to a load output, a switch configured to selectively control the contract, and an indicator. The contact has a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The switch has an on position wherein the contact is controlled to be in the closed position, and an off position wherein the contact is controlled to be in the open position. The indicator provides a normal on status, a normal off status, and an error on status.

摘要： A system for controlling the area circuits that stem from a circuit breaker box in a building. A switch activation unit is provided and is wired to the outgoing wires of a circuit breaker box. The switch activation unit contains a switch for each of the area circuits to be controlled. The switches are wired in series between the circuit breakers in the circuit breaker box and the area circuits. A control unit communicates with the switch activation unit and selectively controls the on/off state of its switches. The control unit is programmable and can activate and deactivate different area circuits at different preprogrammed times. The control unit can also be operated remotely using a link to a smart device.

摘要： Systems, methods, and circuits for determining one or more switch statuses are disclosed herein. In one example embodiment, such a system includes a first port configured to be coupled to a switch, a capacitor, a comparator having first and second input ports and an output port, a current source coupled to the first input port, and a control component. The first input port is coupled to the first port and a threshold voltage if applied to the second input port. The control component is configured so that, in at least one circumstance, it causes the current source to cease driving the current in response to receiving an indication from the output port indicating that an additional voltage applied to the first input port has changed from being less than the threshold voltage to being greater than that voltage, the indication being indicative of the switch status.

摘要： A low-profile electrical contactor is provided comprising at least one electrical contact switch, an actuation means and a current determining device. The or each electrical contact switch has first and second electrical terminals, an electrically-conductive busbar in electrical communication with the first electrical terminal, the busbar having two end faces between which a current can flow in a flow direction and at least two flat sides in parallel with the flow direction, at least one fixed electrical contact which is attached to the busbar, an electrically-conductive moveable arm in electrical communication with the second electrical terminal, and at least one moveable electrical contact which is attached to the electrically-conductive moveable arm to form an electrical contact set with the fixed electrical contact. The actuation means can actuate the electrically-conductive moveable arm of the or each electrical contact switch between open and closed conditions. The current determining device has a first field-modifying element formed of a magnetic material located at or adjacent to the first end face of the busbar, a second field-modifying element formed of a magnetic material and located at or adjacent to the second end face of the busbar, at least one sensing coil at or adjacent to the busbar and the first and second field-modifying elements, and having a coil axis between planes of the first and second flat sides. An electromagnetic field induced by the current flowing in the busbar is modified by the first and second field-modifying elements to extend more or substantially more in parallel with the coil axis of the sensing coil.

摘要： An anti-interference switch signal transmission circuit, in which a changeover switch is used at a signal terminal, is disclosed. A normally closed contact is connected to DC−, a normally open contact is connected to DC+, and a common contact is connected to a switch signal acquisition circuit. When no signal exists, DC− is provided to a positive input terminal of the switch signal acquisition circuit via the normally closed contact. Since a negative input terminal of the switch signal acquisition circuit is also connected to DC−, even if interference is caused, no false signal is generated. When a signal exists, the position of the changeover switch changes and DC+ is connected to DC− via the closed normally open contact through the switch signal acquisition circuit thus a loop is formed, so that the signal can be detected.
