Abstract
The present invention provides a spring for a tripping mechanism in a circuit breaker for connection to a circuit. The tripping mechanism has a first component which is accelerated along a predetermined path of travel to a trip release velocity upon occurrence of a trip event in the circuit and a second component which is initially stationary prior to engaging the first component. The spring includes a body for decreasing the trip release velocity of the first component prior to engaging the second component. A tripbar for a tripping mechanism in a circuit breaker for connection to a circuit is also provided. The tripping mechanism has an armature which is accelerated along a predetermined path of travel to a trip release velocity upon occurrence of a trip event in the circuit while the tripbar is initially stationary prior to engaging the first component. The tripping mechanism further includes a spring having at least two ends. The tripbar includes an elongated body having a surface which has a slot for inserting one end of the spring therein. The present invention also provides a trip assembly for a circuit breaker for connection to a circuit. The trip assembly includes a first component which is set in motion along a predetermined path of travel to a trip release velocity by a trip event in the circuit. A second component is initially stationary prior to engagement with the first component. The assembly also includes decreasing the trip release velocity of the first component before it engages a second component.
