    Abstract: A low voltage circuit breaker is provided. The low voltage circuit breaker includes a contact system with a first contact and a second contact that are electrically connectable and disconnectable relative to one another. The first contact includes a body having a first layer and a second layer, wherein the first layer is arranged on the second layer and is configured to come in contact with the second contact for providing the electrical connection with the second contact. The first layer has a first material composition having an Ag content that is higher than an Ag content of a second material composition of the second layer. Further, the first material composition has a WC content that is lower than a WC content of the second material composition.

    Abstract: There is a need in homes and small businesses for simple devices to help residents in emergency situations. Extended power outages are an example. “SAVUS” is a simple, safe, low cost device to connect emergency power to an entire home. Current emergency power solutions are costly and usually require complex installation. SAVUS has models which install into most residential type circuit breaker front panels and require only one available circuit breaker space for installation. SAVUS mechanically interlocks with the main circuit breaker and will not allow connection of an external power source to the circuit breaker box until utility power is turned off for safety. Because it is on the house side of the main circuit breaker and completely enclosed with other circuit breakers, utility approval is not normally required. We believe SAVUS may become nearly as common in homes as smoke detectors.

    Abstract: A remotely controllable circuit breaker with an improved space saving structure comprises first and second movable contacts 11 and 12 which are held respectively on first and second contact arms 31 and 32 and are driven individually by a switching mechanism 20 including a manual handle 22 with a contact tripping capability and by a remote control signal responsive electromagnet 60. An L-shaped actuator 80 with a horizontal member 81 and a vertical member 83 is provided to operatively connect the second contact arm 32 to an axially movable core 63, the output member of the electromagnet 60. The actuator 80 is pivoted at its connection between the horizontal and vertical members 81 and 83 and carries the second contact arm 32 on its vertical member 83 for pivotal movement of the second contact arm 32 between operative and inoperative positions respectively enabling and disabling the contact closing. The electromagnet 60 is arranged in side-by-side relation to the switching mechanism 40 with the first and second contact arms 31 and 32 interposed therebetween. The actuator 80 is located in proximity to the electromagnet 60 with the vertical member 83 extending over the lengthwise dimension or the axial direction of the core 63 and with the horizontal member extending over the width dimension of the electromagnet 60 to thereby accommodate the substantial portion of the actuator 80 within the lengthwise and widthwise dimensions of the adjacently disposed electromagnet 60.

    Abstract: A trip unit for a circuit breaker includes a magnetic flux transfer system that employs a permanent magnet(s) and solenoid(s) with a ferromagnetic core. The system generates an attractive force using a solenoid to counter the force of a reset spring and latch friction force when a tripping condition is detected. The generated attractive force together with an attractive force from the magnet attracts a yoke which in turn moves the yoke together with an armature to the tripped position. The system also retains the yoke and armature in the tripped position using the attractive force of the magnet when the generated attractive force is no longer being generated. The system further generates a repulsive force using a solenoid when a resettable condition is satisfied to counter the

    Abstract: A circuit breaker includes a current entry which conducts an electrical current via a wound coil conductor strip of a first coil to a first fixed contact, and includes a contact rocker which can be moved between two switching positions. The contact rocker includes mutually connected contact limbs. A first switching position of the contact rocker, electrically connects the first fixed contact with a second fixed contact which is connected via a wound coil conductor strip of a second coil to a current exit for dissipating an electrical current flowing through the contact limbs of the contact rocker and the coil conductor strips of the coils to a current exit of the circuit breaker. A high electrical current which flows through the wound coil conductor strips of the coils and through the contact limbs of the contact rocker produces a magnetic field which generates a switching force which moves the contact rocker from the first switching position into a second switching position in which the two fixed contacts are electrically separated to interrupt the electrical current.

    Abstract: A transfer switch has a mounting seat, and a main no-fuse circuit breaker, an auxiliary no-fuse circuit breaker, a switching control assembly, and a transmission mechanism mounted on the mounting seat. The switching control assembly selectively switches the main no-fuse circuit breaker and the auxiliary no-fuse circuit breaker. The transmission mechanism has a main transmission set and an auxiliary transmission set. When the switching control assembly is switched to form electrical conduction of the main no-fuse circuit breaker, the main transmission set drives the auxiliary transmission set via a transmission rod to prevent electrical conduction of the auxiliary no-fuse circuit breaker from forming. Likewise, when the electrical conduction of the auxiliary no-fuse circuit breaker is formed, the electrical conduction of the main no-fuse circuit breaker cannot be formed. Accordingly, safety of the transfer switch can be improved when switching between power sources.
