A metering apparatus is connectable to the terminals of a circuit breaker and includes a detection apparatus that is configured to detect a status of the breaker and one or more operational parameters of the breaker. The metering apparatus may further include a communication apparatus that is configured to communicate the status of the breaker and/or one or more operational parameters of the breaker to another device. The metering apparatus may additionally include a power input that is independent of the breaker. Alternatively or additionally, the metering apparatus can be configured to communicate with the other device via any of a variety of established protocols, with the metering apparatus being capable of retrofitting to change the communications protocol by which it communicates with the other device.

A settings emulator for a circuit breaker trip unit includes a handheld enclosure and a plurality of adjustable rotary switches mounted on the handheld enclosure. The adjustable rotary switches define a plurality of different trip settings for the circuit breaker trip unit. A communication channel is also mounted on the handheld enclosure. A microprocessor is enclosed by the handheld enclosure. The processor reads the different trip settings from the adjustable rotary switches and communicates the different trip settings through the communication channel to the circuit breaker trip unit.

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.

A system for monitoring a circuit breaker that includes a monitoring device in electronic communication with the circuit breaker and a receiving device located separately from the monitoring device. The monitoring device receives data from the circuit breaker and wirelessly transmits at least a portion of the data such as one or more phase currents measured from a network which the circuit breaker protects, an ambient temperature within the circuit breaker, and/or data relating to a trip condition of the circuit breaker. The receiving device receives the transmitted data and displays all or a portion thereof. The monitoring device also includes a display that displays all or a portion of the data.

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 &#x2212;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.

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&#xb0; F. for one hour.

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.
