Magnetic member, circuit breaker employing the same, and method of manufacturing the same |
摘要 |
A circuit breaker includes separable contacts and an operating mechanism having a cradle for opening and closing the separable contacts. A trip mechanisms cooperates with the cradle of the operating mechanism to trip open the separable contacts. The trip mechanism includes a bimetal conductor, which is electrically connected in series with the separable contacts. The trip mechanism is responsive to a predetermined condition of current flowing in the bimetal conductor. The trip mechanism also includes a magnetic yoke coupled to the bimetal conductor, an armature pivotally mounted to the magnetic yoke, and a spring biasing the armature away from the magnetic yoke. The spring is set apart from the bimetal conductor. The spring is coupled to the armature and engages the magnetic member.
