Abstract (en)
[origin: ES8705157A1] A moulded case low voltage circuit breaker for high currents has no arcing contacts and is equipped with arc blow-out means drawing the arc very quickly away from the contacts. An insulating shield associated with the moving contact forms an arc formation chamber of a small volume which is open in the direction of the arc chute. The moving and stationary contacts are fitted with arcing horns constituting a small divergent path in proximity to the contacts favoring rapid displacement of the arc, this divergent path leading to an area defined by a hump of the horn. In this area, the clearance of the arcing horns is smaller than the clearance between the contacts as soon as the latter separate to avoid any rearcing on these contacts.
