Abstract: 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.

Abstract: 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.

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.

Abstract: 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.

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.

The double break contacts are provided in series with each other and an overcurrent measurement device such that if an overcurrent is measured, the contacts are simultaneously opened (i.e., double break) to lower the voltage that is developed across each of the sets of contacts. A handle is provided for simultaneously resetting and closing the sets of contacts.

Abstract: A DC voltage circuit interrupter that provides polarity insensitive arc suppression. The circuit interrupter includes two permanent magnets that are positioned in proximity to each of the contacts in the circuit interrupter and is designed to urge an arc that develops between the contacts either toward a first arc extinguisher or a second arc extinguisher depending on the polarity of the applied DC voltage. The circuit interrupter being quick to assemble, light-weight and relatively inexpensive and easy to mount.

Abstract: A circuit interrupter having at least two sets of contacts that are electrically connected in series such that when the at least two sets of contacts are opened, they are opened simultaneously. This functions to increase the distance between the sets of contacts as the distance is additive for the series connected sets of contacts, which increases the arc voltage for breaking any arc that may form between the individual sets of contacts more effectively.

The channel is disposed on the second side of the rocker and has a first end and a second end. A pivot point is disposed on a crank. A pin, disposed on the crank, is located in a first side of the channel. The depression of the first end of the rocker causes a rotational movement of the channel in a curvilinear path around the pivot point, causing a rotational movement of the crank, moving the pin from the first end of the channel toward the second end of the channel.

Abstract: A circuit breaker having a movable contact arm for opening and closing the circuit which is controlled separately by a circuit breaker mechanism for circuit protection and by a switch lever mechanism which does not require actuation of the circuit breaker mechanism to function. The switch lever may also be activated remotely by a remote actuator, for example, a solenoid. A manual reset mechanism is provided so that, actuation of which, when power has been lost to the remote actuator when the remote actuator is in the off position, moves the remote actuator to the on position, thereby resetting the circuit to the closed state.
