Abstract
Abstract This invention provides a circuit breaker comprising separable contacts, a releasable mechanism, releasable to effect a tripping operation automatically opening the contacts and an electromechanical trip means operable to release the mechanism. A shock absorbing means is also provided that effectively isolates the flux transfer and magnetic trip actuator from shock and vibration.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
105 words
A circuit interrupter, comprising: (a) housing means; (b) contact means disposed within said housing means for being actuated to an opened state; (c) manual actuating means disposed in said housing means to be moved to actuate said contact means; (d) electromechanical trip means disposed in said housing means to be electromechanically moved to actuate said contact means and to provide an associated trip indication; and (e) shock absorbing means generally comprised of a leaf spring connected to said electromechanical trip means so it is disposed to absorb the shock and vibration when said manual actuating means is manually operable to open and close said contacts.
