Abstract
The invention concerns an overcurrent protection device which comprises contacts adapted to operate in dependence on the current. The set of contacts are arranged in a vacuum vessel, with one of the contacts guided movably via an actuator rod through an end wall of the vessel, while the other is secured to the opposite end. The moving rod cooperates with a latching device, which holds the contact in the open position. The latching device is designed so that it can be released when desired. If an overcurrent occurs, the contacts are separated by electrodynamic forces and are secured in the separated position by the latching device. After release of the latching device, the overcurrent protection device is again ready for use.
