A novel current limiting PTC polymer device and methods of making the same comprising a current limiting polymer composition with porous electrodes interfaced therewith such that a low contact resistance results using a combination of (1) extrusion attachment of the current limiting polymer composition to the porous electrodes, (2) careful selection of the electrode materials in view of the conductive filler and/or conductive metal particles in the current limiting polymer composition, and (3) plasma treatment of the attachment surfaces of the current limiting polymer composition preceding and/or during the extrusion attachment process. The invention provides for the selective treatment of portions of the surface of the current limiting polymer composition by at least one of plasma etching and metallizing to create attachment surfaces for extrusion attachment of porous electrodes resulting in a low contact resistance, mechanical stability and a reduced potential for arcing in the electrode/polymer interface. The electrical devices of the invention are particularly useful in circuit protection applications.

An apparatus detects arcing faults at a first wavelength. A light source provides modulated light at a second different wavelength and a first frequency. An optical fiber receives the modulated light and gathers ambient light at both wavelengths. A splitter receives and splits the received light into first and second beams. A first filter extracts from the first beam a first filtered beam including the first wavelength. A first photodetector generates a first electrical signal from the first filtered beam. A second filter extracts from the second beam a second filtered beam excluding the first wavelength. A second photodetector generates a second electrical signal from the second filtered beam. A low pass filter extracts from the second electrical signal a third electrical signal representative of light at the second wavelength excluding the modulated light. A comparator generates an arcing signal when the first electrical signal exceeds the third electrical signal.

A contact assembly for a circuit breaker includes a fixed contact, a movable contact, and a movable contact arm. The movable contact arm includes a first end carrying the movable contact, a second end, and a pivot portion proximate the second end. A moving arm portion extends from the first end toward the pivot portion. The moving arm portion has a width, an upper edge, a lower edge, and a height defined by the distance between the upper edge and the lower edge. In response to a trip condition, the movable contact separates from the fixed contact and the movable contact arm pivots open at an angular opening velocity. The height of the moving arm portion of the movable contact arm is at least four times the width of the moving arm portion, thus minimizing the moment-of-inertia of the movable contact arm, and increasing the angular opening velocity.

A shunt assembly is provided for an electrical switching apparatus including a conductor assembly having a load conductor and a movable contact assembly with a number of movable contact arms. The movable contact assembly is movable in response to a fault current. The shunt assembly includes a number of flexible conductive elements each having a first end electrically connected to the load conductor, a second end electrically connected to a corresponding one of the movable contact arms, and a number of bends disposed between the first and second ends. At least one constraint element is disposed proximate a corresponding one of the bends and constrains movement of the flexible conductive element in response to the fault current, thereby translating the magnetic repulsion force associated with the fault current into a corresponding torque of the movable contact arms of the movable contact assembly.

An apparatus is for a power circuit providing an alternating current to a load. The apparatus includes a high frequency current sensor structured to cooperate with the power circuit to provide a high frequency current signal. A voltage zero crossing detector is structured to cooperate with the power circuit to provide a voltage zero crossing signal. A high pass filter is structured to provide a filtered current signal from the high frequency current signal. A threshold comparator is structured to provide an output when the filtered current signal exceeds a predetermined value. A processor is structured to receive the voltage zero crossing signal and the output of the threshold comparator and output a trip signal in response to undesired series arcing by detecting an unsymmetrical high frequency signal for a predetermined number of cycles.

A triggered arc flash arrester includes an envelope structured to operate at: a pressure less than about 1.33 Pa; or a pressure greater than 0.10857 MPa; a plurality of conductors partially disposed within the envelope; a number of gaps disposed between the plurality of conductors within the envelope; and a shorting structure selected from the group consisting of a triggered gap and a fuse. The shorting structure is operatively associated with the number of gaps. The shorting structure is structured to electrically short the plurality of conductors either together or to ground, in order to create an arc within the envelope which is electrically in parallel to an arc fault causing the arc fault internal to switchgear to be extinguished.
