A circuit interrupter has first and second contacts that are actuatable relative to each other between a closed position wherein a power source and a load are in electrical communication and an open position wherein the power source and the load are not in electrical communication. An arc extinguisher is also provided for extinguishing an arc that develops in the vicinity of the contacts. An electromagnetic coil, when energized, generates a magnetic field that permeates an area where the arc develops, the magnetic field urging the arc toward the arc extinguisher regardless of a polarity of the contacts. An auxiliary switch is operably connected to the contacts, such that upon movement of the contacts relative to each other from the closed position toward the open position, the auxiliary switch is activated so as to energize a circuit feeding power to the electromagnetic coil, thereby generating the magnetic field.

A circuit breaker design allows for the circuit breaker to have an overall height (i.e., measured vertically along the circuit breaker's exposed outwardly-facing surface in the typical orientation of circuit breaker panels) that is slimmer than achievable with known typical configurations, while at the same time still providing robust power (e.g., voltage) handling and arc interruption capabilities. This is achieved, for example, by providing various components formed from polymer materials (which are generally less conductive of heat than metals), reinforced by metal members in certain areas, if needed, as well as a very particular configuration of a permanent magnet that is employed for enhanced arc quenching.

Slim circuit breaker

A circuit interrupter includes a first set of contacts connected in series with a second set of contacts, with both sets of contacts configured to open and close simultaneously. First and second arc extinguishers are associated with the first and second sets of contacts, respectively. A moveable permanent magnet moves as the sets of contacts simultaneously open and close, the moveable magnet generating a moveable magnetic field, a first stationary permanent magnet associated with the first arc extinguisher, the first stationary magnet generating a first stationary magnetic field, where the first stationary magnetic field and the moveable magnetic field are additive, and a second stationary permanent magnet associated with the second arc extinguisher, the second stationary magnet generating a second stationary magnetic field, where the second stationary magnetic field and the moveable magnetic field are also additive.

A circuit interrupter adapted to be detachably connected to a rail system includes a housing having a notch disposed thereon adapted to receive a first leg of the rail system. An engagement member having a notch disposed therein adapted to receive a second leg of the rail system is slideably carried by the housing such that the notch in the engagement member is moveable in a first plane toward and away from the notch in the housing between an engaged position and a disengaged position. An actuation member is slideably carried by the housing and is moveable in a second plane, different than the first plane, between an actuated position and an unactuated position, movement of the actuation member in the second plane being translated into movement of the engagement member in the first plane.

A circuit interrupting device includes line and load terminals and an interrupter electrically coupled therebetween, the interrupter having open and closed conditions. The device also includes a fault detector configured to detect a fault in an electrical signal in the load circuit. When such a fault is detected, the fault detector causes actuation of the interrupter to the open condition. A communication interface is adapted to receive a remote test command signal, and a processor generates, in response to receipt of the remote test command signal, a simulated fault in the load circuit, such that the fault detector attempts to cause actuation of the interrupter to the open condition. The processor determines whether or not the fault detector successfully caused actuation of the interrupter to the open condition in response to receipt of the remote test command signal, and if not, generates an alarm signal indicative of a malfunction.

A latching relay includes first and second coils and a common plunger operatively connected therebetween such that activation of the first coil moves the plunger in a first direction and activation of the second coil moves the plunger in a second direction, opposite the first direction, the first and second directions lying in a first plane. A limit switch includes a common contact and first and second coil contacts, where a position of the common contact is alternately switched between electrical connection to either the first or second coil contact based on a position of the plunger. A slide toggle accessible by a user is operatively connected to the plunger and slideable together with the plunger such that actuation of the slide toggle by the user causes manual actuation of the plunger. The slide toggle is slideable in a second plane parallel to the first plane.

A circuit interrupter electrically connects a line terminal to a load terminal in a closed condition and electrically disconnects the line terminal from the load terminal in the open condition. A controller includes a fault detector configured to detect a fault in an electrical signal in a load circuit, such that when a fault is detected on the load circuit, the fault detector causes actuation of the interrupter to the open condition. The controller is adapted to receive an off command, and in response to the off command, generate a simulated fault in the load circuit, such that the fault detector causes actuation of the interrupter to the open condition, such that one and the same interrupter is employed for both fault tripping and commanded tripping.

Remote operated ground fault circuit breaker

A fault detector test device includes a test switch including a pivotable lever arm having a first end pivotably connected to rotate about an axis and a second end pivotable in an arc around the axis between an active position and an inactive position. A slide member has a first end accessible by an operator and a second end that cooperates with the second end of the lever arm, the slide member being slideable with respect to the axis of the lever arm such that the second end of the slide member slides in a plane that is substantially tangential to the arc in which the second end of the lever arm pivots. The second end of the slide member and the second end of the lever arm cooperate such that generally planar sliding motion of the slide member is translated into pivoting motion of the lever arm.

Circuit breaker with slide to test function

A circuit breaker design allows for the circuit breaker to have an overall width (i.e., measured along the circuit breaker's exposed outwardly-facing surface of its housing) that is narrower than achievable with known typical configurations, while at the same time still providing robust arc interruption capabilities. This is achieved in large part by providing a specific orientation of a moveable contact arm assembly and/or by providing a specific configuration of a current path within the housing.

A circuit interrupter includes a stationary contact and a moveable contact disposed on a moveable contact arm, the moveable contact being configured to be pivotable into and out of physical contact with the stationary contact by pivoting of the moveable contact arm about an axis. The moveable contact arm defines a pivot angle with respect to the stationary contact as the moveable contact arm pivots about the axis. A biasing member exerts a biasing force on the moveable contact arm which pivotally biases the moveable contact toward the stationary contact when the pivot angle is less than a zero-bias angle and which pivotally biases the moveable contact away from the stationary contact when the pivot angle is greater than a zero-bias angle.

Circuit breaker with snap action contacts

A circuit interrupter having a status indicator providing a current status of the circuit interrupter, the status indicator presenting one of: an On state, an Off state or a Fault state. The status indication is provided as a visual status and is color coded to one of the three circuit interrupter states. The circuit interrupter further including, in one configuration, a rocker actuator that rotates about an axis and the status indication mechanism is coupled to the rocker actuator.

Circuit interrupter with status indication

A circuit interrupter includes a stationary contact and a moveable contact arm assembly having a moveable contact positioned thereon, the moveable contact configured to be moveable into and out of physical contact with the stationary contact. The circuit interrupter also includes an overcurrent tripping device coupled to the moveable contact arm assembly via a linkage assembly and configured to move the moveable contact out of physical contact with the stationary contact upon detection of an overcurrent situation. The moveable contact arm assembly is connected to the linkage assembly via at least two pivots positioned on the contact arm assembly, so as to cause a relative sliding action between the moveable and stationary contacts as the moveable and stationary contacts are moved into or out of contact with each other such that a wiping action is created in order to clean the moveable and stationary contacts.

Low profile circuit breaker with self cleaning contacts

A latching relay includes a first coil, a second coil and a common plunger operatively connected between the first and second coils such that activation of the first coil moves the plunger to a first position and activation of the second coil moves the plunger to a second position. The latching relay also includes a limit switch having a common contact and first and second coil contacts. A position of the common contact is alternately switched between electrical connection to either the first or second coil contact based on a position of the plunger. The first and second coil contacts are electrically connected to the first and second coils, respectively such that when electrical power is applied to the common contact, the electrical power is alternately applied to either the first coil or the second coil depending on the position of the common contact.
