摘要: Provided herein are thermally protected varistor (TPV) devices including a varistor body and a terminal assembly directly coupled together. The terminal assembly may include a housing, wherein an opening is provided in a base of the housing. A lead is coupleable with the varistor body via a thermal linking material positioned within the opening of the base, the thermal linking material operable to maintain direct physical contact with the lead when the thermal linking material is below a melting point. The terminal assembly may further include a shield slidable within the housing between a first position and a second position, wherein in the first position the shield is positioned adjacent the thermal linking material, and in the second position the shield is positioned between the lead and the second side of the varistor body. The shield includes a tab for releasably coupling the shield to the housing.

摘要: A power resistor comprises a tubular housing composed of metal and a resistor element received therein, wherein the housing has four side walls that extend along a longitudinal axis of the housing between two ends and define a rectangular cross-section. The housing comprises four edges of the four side walls at at least one of the two ends. Two of the four side walls have a respective incision at their edges for introducing a fastening element and the two other side walls have a respective clearance in alignment with the oppositely disposed incision to facilitate a placement of a tool at a fastening element introduced into the respective incision.

摘要: The invention relates to an overvoltage protection device with varistors, wherein a first varistor and a second varistor are connected in series, wherein the first varistor has a thermal disconnector, wherein the first varistor has a lower operating voltage than the second varistor, and wherein the first varistor has a lower energy absorption capacity than the second varistor, with the first varistor heating up more in the event of an overload and thereby causing the thermal disconnector to disconnect.

摘要: A varistor module includes a base, a case, and a varistor body. The base and the case are assembled with each other to form a closed space. The varistor body includes a plurality of ceramic chips and a bridging element. The ceramic chips are disposed in the closed space. Each ceramic chip has an electrode layer on two opposite sides, respectively. The bridging element has at least two bridging segments and a crossing segment. The bridging segments are connected to electrode layers of different ones of the ceramic chips. The crossing segment is disposed between the bridging segments.

摘要: A terminal-thermistor assembly may include a thermistor and a terminal. The thermistor may include a body encasing a temperature-sensing element. The terminal may include a shaft and a housing disposed on an end of the shaft. The housing may include a cavity, a protrusion extending into the cavity and a cantilevered spring element. The spring element may be resiliently flexible between a first position in which a space between the spring element and the protrusion is less than a thickness of the body of the thermistor and a second position in which the space between the spring element and the protrusion is equal to the thickness of the body. A first surface of the thermistor body may contact the spring element and a second surface of the thermistor body opposite the first surface may contact the protrusion when the body is received within the cavity.
