ELECTRICAL CIRCUIT BREAKERS |
摘要 |
An electrical circuit breaker includes a moveable contact piece connected to an actuating means and provided with a contact face arranged to make contact with a contact face of a second contact piece by movement generally in a first direction. The circuit breaker further includes an electrical connector for conveying current to the moveable contact piece, the electrical connector including at least two adjacent limbs adapted to convey the current in substantially opposing directions so as to generate an electromagnetic force repelling said adjacent limbs from one another. This repelling force is used to assist in maintaining the contact faces in abutment. In addition, when the actuator is operating to open the contacts, the repelling force is operative to accelerate the actuator for a first part of its stroke.
