摘要： A current transformer includes a CT core having a central opening, a height, a width, inner and outer radii, and a secondary winding disposed about the CT core. The CT core is formed from a winding of an elongated length of taped steel having a reluctance and a width. The CT core height corresponds to the taped steel width. The CT core width is equal to the difference between the outer and inner radii. An air gap having a reluctance, a width and a depth is disposed in the CT core. The depth is along a portion of the CT core height. The air gap width is substantially smaller than the CT core height and width. The air gap reluctance is substantially greater than the taped steel reluctance. The CT core has a permeability resulting from being annealed at a temperature of 1450 to 1550° F. for one hour.

摘要： A circuit breaker includes for each neutral and phase power conductor, a current sensor sensing an alternating current flowing in a corresponding power conductor, a comparator determining whether the sensed alternating current is positive or negative, a rectifier rectifying the sensed alternating current to provide a rectified current value, and an analog-to-digital converter converting the rectified current value to a signed digital value having a positive sign. A processor cooperates with the comparators and the analog-to-digital converters and includes a routine that changes the positive sign of the signed digital value to a negative sign if the sensed alternating current is negative, adds the signed digital value for each power conductor to provide a sum, and employs the sum to determine whether to output a ground fault signal. The processor further cooperates with an operating mechanism to trip open separable contacts responsive to the ground fault signal.

摘要： A shield is provided for a circuit breaker including a printed circuit board (PCB). The PCB is a generally planar member with a plurality of electrical components each having a corresponding shape. The shield includes at least one resilient sheet member at least partially covering the generally planar member and at least one of the electrical components coupled thereto. The resilient sheet member generally conforms to the corresponding shape of the at least one of the electrical components in order to shield and protect it from debris and to resist accumulation of gas-carried carbon. The resilient sheet member is made from a material, such as silicon rubber, which is flexible and elastic within a temperature range of about −70 to about 450 degrees Fahrenheit, and it is flame-resistant, tear and abrasion-resistant, impervious to moisture and chemicals, fungus-resistant, and resistant to outgassing.

摘要： A rotating display device displays a value in a variable viewing orientation. The value is received from an electrical apparatus, such as a circuit breaker, having a first port. The rotating display device includes a housing having a first side and a second side, a display disposed on the first side of the housing, a rotating assembly disposed on the second side, and a second port for receiving the value from the first port of the electrical apparatus. The second port communicates with the display and is coupled to the rotating assembly in order to permit the display to rotate. The rotating assembly permits the rotating display device to rotate in the plane of the surface of the circuit breaker on which it is mounted, thereby permitting the display to be quickly and accurately viewed and interpreted regardless of the orientation of the surface to which it is coupled.

摘要： A trip actuator assembly is provided for an electrical switching apparatus, such as a circuit breaker. The trip actuator assembly includes a trip actuator with an actuating element, which is movable among unactuated and actuated positions corresponding to separable contacts of the circuit breaker being closeable and tripped opened in response to a trip condition, respectively. The trip actuator is disposed at a mounting portion of a frame. An interface assembly is movably coupled to the frame and includes an interface element disposed between the actuating element of the trip actuator and a portion of the circuit breaker operating mechanism. When the actuating element moves from the unactuated position toward the actuated position, it engages and moves the interface element, thereby moving the operating mechanism to trip open the separable contacts. The frame secures the trip actuator assembly in a desired orientation within a corresponding one of the housing compartments.

摘要： A trip unit includes a housing, a rotary plunger mounted in the housing and a pivotal trip bar also mounted therein. The trip bar latches the plunger in an on position, releases the plunger to a tripped position and re-latches the plunger. A set of springs biases the plunger to the tripped position. A rotary trip lever is pivotally mounted in the housing. A trip solenoid includes a linear plunger, which resets the solenoid when retracted, and which engages and rotates the trip lever when extended, in order to rotate the trip bar and release the rotary plunger. The rotary plunger engages the rotary trip lever when reset and rotates the same in an opposite direction, in order to retract the linear plunger and reset the solenoid. During that reset operation, the rotary plunger also cams the trip bar, in order to re-latch the rotary plunger in the on position.
