    Abstract: A method of detecting arcing conditions includes sensing current and HF signals therefrom; bandpass filtering the HF signals and providing filtered signals; detecting peak signals and envelopes from the filtered signals; counting occurrences of the envelopes exceeding a first value; maintaining temporary values corresponding to the peak signals; determining a trip time as a function of the current; determining if any peak signal is greater than a second value, and responsively increasing a temporary value and, otherwise, decreasing the temporary value; determining if a predetermined function of the temporary values is greater than a fifth value, and adding the temporary values to an accumulator, and otherwise, decreasing the accumulator; and tripping open the power circuit if: a difference between the occurrences of current and immediately previous half cycle having the same polarity is at least two, the accumulator is greater than a seventh value, and the trip time is reached.

    Abstract: A circuit breaker includes fixed and movable contacts, an operating mechanism including a movable arm carrying the movable contact, an arc chute including a plurality of spaced apart first and second arc plates, and a slot motor. A slot motor structure is disposed about the contacts and a portion of the movable arm. An insulative housing at least substantially covers and insulates the slot motor structure from the movable arm and contacts. The inslulative housing includes a base and a pair of arms disposed therefrom. Each of the arms includes a first portion disposed proximate the first arc plates and a second smaller portion disposed proximate the second arc plates. A space extending from the first portion, not occupied by the second portion, is generally occupied by a portion of the second arc plates. The second portion forms a debris shield between the second arc plates and the operating mechanism.

    Abstract: An electrical switching apparatus (14A;20;22;34;64;1 18;120;142) comprises: a first terminal (40); a second terminal (42); separable contacts (44) electrically connected between the first terminal and the second terminal; an operating mechanism (46) structured to open and close the separable contacts; and an arc fault trip circuit (48) cooperating with the operating mechanism and structured to trip open the separable contacts responsive to an arc fault condition. An inductor (32) is electrically connected in series between the first terminal and the second terminal. A capacitor (30) includes a first lead (50) electrically connected between the inductor and the second terminal, and a second lead (52) electrically connected to a ground or neutral conductor. The inductor and the capacitor are structured to cooperate with a power circuit impedance (56) downstream of the second terminal to form a filter trap circuit (58).

    Abstract: A circuit breaker includes separable contacts, an operating mechanism structured to open and close the separable contacts, a molded enclosure comprising a first molded portion and a second molded portion, a plurality of thread cutting screws fastening the first molded portion to the second molded portion, and a plurality of machine screws. The first molded portion and the second molded portion cooperate to form a plurality of exterior walls. The exterior walls define an interior volume, which encloses the separable contacts and at least a portion of the operating mechanism. The machine screws extend within and reinforce the exterior walls and restrict expansion of the exterior walls away from the interior volume.
