Abstract
A magnetic release system for a circuit breaker, the magnetic release system includes a contact structure; a strap configured to conduct a first level of electrical current and a second level of electrical current; a u-shaped collar having a pole face, the u-shaped collar disposed around the strap; a release lever disposed proximate the pole face, the release lever rotatably mounted on the strap; wherein the release lever is releasably engaged with the contact structure; and wherein the release lever prevents movement of the contact structure at the first level of electrical current and releases the contact structure at the second level of electrical current.
Claims20
A magnetic release system for a circuit breaker, said magnetic release system comprising:
- a contact structure;
- a strap configured to conduct a first level of electrical current and a second level of electrical current;
- a u-shaped collar having a pole face, said u-shaped collar disposed around said strap;
- a release lever disposed proximate said pole face, said release lever rotatably mounted on said strap;
- wherein said release lever is releasably engaged with said contact structure;
- and
- wherein said release lever prevents movement of said contact structure at said first level of electrical current and releases said contact structure at said second level of electrical current.
A circuit breaker comprising:
- a first contact structure in contact with a second contact structure;
- and
- a magnetic release system arranged to separate said first contact structure and said second contact structure, said magnetic release system comprising:
- a strap configured to conduct a first level of electrical current and a second level of electrical current,
- a u-shaped collar having a pole face, said u-shaped collar disposed around said strap,
- a release lever disposed proximate said pole face, said release lever rotatably mounted on said strap,
- wherein said release lever is releasably engaged with said second contact structure, and
- wherein said release lever prevents movement of said second contact structure at said first level of electrical current and releases said second contact structure at said second level of electrical current.
A circuit breaker comprising:
- a first contact structure in contact with a second contact structure;
- and
- a magnetic release system arranged to separate said first contact structure and said second contact structure, said magnetic release system comprising:
- a strap configured to conduct a first level of electrical current and a second level of electrical current,
- a u-shaped collar having a pole face, said u-shaped collar disposed around said strap,
- a release lever disposed proximate said pole face, said release lever rotatably mounted on said strap,
- means for releasably engaging said release lever with said second contact structure, and
- means for preventing movement of said release lever at said first level of electrical current and releasing said release lever at said second level of electrical current.
