    Abstract: An arc fault detection system includes a high frequency detector module structured to detect first spectral content of power having a frequency in a first frequency range, a number of arc fault circuit interrupters each having separable contacts, a low frequency detector module structured to detect second spectral content of power having a frequency in a second frequency range, a control unit structured to control the separable contacts to trip open, and an arc fault detection unit structured to detect an arc fault based on the detected first and second spectral content of the power and to cause the control unit to control the separable contacts to trip open in response to detecting the arc fault. A communication bus provides communication between the high frequency detector and the arc fault circuit interrupters and the first frequency range includes frequencies that are higher than frequencies in the second frequency range.

    Abstract: A modular circuit breaker includes a module assembly coupled to a primary assembly. The primary assembly includes a primary housing, separable contacts disposed therein, a first terminal conductor electrically connected to one of the separable contacts, a conductive tab electrically connected to another one of the separable contacts and which extends outward from a first end of the primary housing, an operating mechanism disposed in the primary housing for selectively opening and closing the separable contacts, and a trip mechanism disposed in the primary housing cooperative with the operating mechanism to trip open the separable contacts. The module assembly includes a module housing having a second terminal conductor positioned therein and electrically connected to the conductive tab, a third terminal conductor structured to be electrically connected to a neutral conductor of a load, and a fourth terminal conductor structured to be coupled to a neutral bus.

    Abstract: An electronic overload current breaker supports arc-fault and ground-fault (AFGF) detection along with built-in shunt calibration (BISC™). The breaker may include a current sensing shunt and a control circuit electrically coupled to the current sensing shunt. This control circuit is configured to calibrate the current sensing shunt in response to application of a calibration current to the breaker. The control circuit can: (i) determine a magnitude of the calibration current applied to the breaker, (ii) map the magnitude of the calibration current to a first one of a plurality of current ratings for the breaker, and (iii) set the breaker to monitor overload conditions at the first one of the plurality of current ratings. The plurality of current ratings for the breaker can be less than the magnitude of the calibration current.

    Abstract: Plug-on ground fault modules are configured with a housing and at least one ground fault terminal. The at least one ground fault terminal can be a rigid or semi-rigid member that is configured to slidably engage a circuit breaker terminal. The modules also include aground fault circuit coupled to the ground fault terminal and at least one printed circuit board in the housing with components of the ground fault circuit including at least one solenoid assembly coupled thereto with a respective magnetized or magnetic plunger member residing on or adjacent thereto, and at least one current transformer. The modules also include at least one collar assembly residing in the housing spaced apart from the solenoid assembly and plunger member that is arranged to be able to engage a lever in the circuit interrupter to delatch the circuit interrupter.
