Abstract
A fastening assembly is for a circuit breaker. The circuit breaker has a base and a bimetal. The fastening assembly includes a heater element structured to be coupled to the bimetal and the base, and a plurality of fastening members including a nut and a coupling member coupled to the nut. The nut is structured to be disposed between the heater element and the bimetal. The coupling member extends through the heater element and into the nut in order to minimize movement of the heater element with respect to the base.
Claims18
A fastening assembly for a circuit breaker, said circuit breaker comprising a base and a bimetal, said fastening assembly comprising:
- a heater element coupled to said bimetal and said base;
- and
- a plurality of fastening members comprising a nut and a coupling member coupled to said nut, said nut being disposed between said heater element and said bimetal, said coupling member extending through said heater element and into said nut in order to minimize movement of said heater element with respect to said base,
- wherein said nut comprises a stabilizing portion and a post portion extending outwardly from said stabilizing portion and away from said bimetal.
A fastening assembly for a circuit breaker, said circuit breaker comprising a base and a bimetal, said fastening assembly comprising:
- a heater element coupled to said bimetal and said base;
- and
- a plurality of fastening members comprising a nut and a coupling member coupled to said nut, said nut being disposed between said heater element and said bimetal, said coupling member extending through said heater element and into said nut in order to minimize movement of said heater element with respect to said base,
- wherein said coupling member is a screw;
- wherein said screw comprises a head portion and a threaded portion extending from said head portion;
- and wherein said heater element is disposed between said head portion and said nut.
A circuit breaker comprising:
- a base;
- a bimetal;
- and
- a fastening assembly comprising:
- a heater element coupled to said bimetal and said base, and
- a plurality of fastening members comprising a nut and a coupling member coupled to said nut, said nut being disposed between said heater element and said bimetal, said coupling member extending through said heater element and into said nut in order to minimize movement of said heater element with respect to said base,
- wherein said nut comprises a stabilizing portion and a post portion extending outwardly from said stabilizing portion and away from said bimetal;
- and wherein said stabilizing portion engages said base in order to prevent said nut from rotating with respect to said base.
A circuit breaker comprising:
- a base;
- a bimetal;
- and
- a fastening assembly comprising:
- a heater element coupled to said bimetal and said base, and
- a plurality of fastening members comprising a nut and a coupling member coupled to said nut, said nut being disposed between said heater element and said bimetal, said coupling member extending through said heater element and into said nut in order to minimize movement of said heater element with respect to said base,
- wherein said coupling member is a screw;
- wherein said screw comprises a head portion and a threaded portion extending from said head portion;
- wherein said heater element is disposed between said head portion and said nut;
- wherein said plurality of fastening members further comprises a plate member having a first surface and a second surface opposite and parallel to said first surface;
- wherein said first surface engages said heater element;
- and wherein said second surface engages said head portion of said screw.
A method of assembling a circuit breaker comprising the steps of:
- providing said circuit breaker with a base, a bimetal, and a fastening assembly, said fastening assembly comprising a heater element coupled to said bimetal and said base, and a plurality of fastening members comprising a nut and a coupling member;
- disposing said nut between said heater element and said bimetal;
- and
- extending said coupling member through said heater element and into said nut in order to minimize movement of said heater element with respect to said base,
- wherein said nut comprises a stabilizing portion and a post portion extending outwardly from said stabilizing portion and away from said bimetal.
