Abstract: Described herein is a switch pole for a low voltage switching device including an insulating casing defining an internal space with a contact area and an arc-extinguishing area of the switch pole, a fixed contact assembly and a movable contact assembly positioned in the contact area and including, respectively, one or more fixed contacts and one or more movable contacts, which can be mutually coupled or uncoupled, and an arc chamber positioned in the arc-extinguishing area that includes a plurality of parallel arc-breaking plates. The insulating casing includes an insulating wall partially separating the contact area from the arc-extinguishing area and a channel connects the contact area to the arc-extinguishing area. The switch pole further includes an additional arc-breaking element anchored to the insulating wall, passing through the channel of the insulating wall and arranged in electrical connection with a terminal arc-breaking plate of the arc chamber.

Abstract: A low voltage contact assembly including a rotating support having a body adapted to rotate around a rotation axis and supporting at least a first couple of movable contacts that can be coupled to/uncoupled from corresponding first fixed contacts by rotation around said rotation axis, the first couple of movable contacts including a first and a second movable contacts housed in the rotating support and each having a corresponding first and second elongated contact body with a contact end protruding from the rotating support, the first and second elongated contact bodies lying parallel to each other in a rotation plane substantially perpendicular to the rotation axis. The low voltage assembly further includes a pressure exerting device having a pressing bar operatively coupled to the first and second elongated contact body and transversally placed with respect to the rotation plane of the first and second elongated contact bodies, and a first and a second elastic elements positioned at opposite ends of the pressing bar, the pressing bar further including a first and a second operating surface each including a corresponding first and second pressing surface protruding from the pressing bar and respectively acting on the first and second elongated contact body.
