    • An electrical fault detection device for use in a branch of a power circuit that utilizes signals from an AC line current sensor coupled to an electrical distribution line having a primary and neutral lines, a line high-frequency sensor coupled to the electrical distribution line, a differential current sensor coupled to the primary and neutral lines, and a ground fault current sensor coupled to the primary and neutral lines. A signal conditioner receives the signals outputted by AC current line current sensor, the line high frequency sensor, the differential current sensor and the ground fault current sensor and generates a signal indicative of the load current associated with a branch of the power circuit. Output of the signal conditioner is sampled and processed by a processing resource. The processing resource has stored therein data representing a plurality of time-versus-current curves that define a plurality of regions in which tripping may or may not occur. One region has time data and current data that define a time-duration for a particular current magnitude for which no tripping will occur. Another region has time data and current data that define a time-duration of a particular current magnitude for which tripping will occur. Processing resource processes sampled signal to determine the region to which the processed time data and current data correspond, and generates a signal to initiate tripping if the sampled signal yields a time duration for a particular current magnitude that corresponds to a region for which tripping must occur.

    • A circuit breaker system (100) providing a low impedance magnetic latch tripping scheme. The circuit breaker system (100) includes a trip unit (310) coupled to a switch unit (108). Trip unit (310) is coupled to an electrical circuitry and utilizes a current transformer (114) to sample a current conducting through the electrical circuitry. This current is processed into an input signal (126) suitable as an input to a trip circuitry (316) included in the trip unit (310). When a processor (322) senses an overcurrent condition in the input signal (126), processor (322) transmits a trip signal (128) to a switch (220) to initiate protection against the overcurrent condition, i.e., a trip of the electrical circuitry. Switch (220) permits a low release current to conduct through a low impedance electromechanical interface unit (218) such that the electromechanical interface unit (218) can actuate a mechanical opening mechanism included in the switch unit (108).
