A vacuum cartridge () is manufactured with a dielectric coating () made from elastomer directly on the enclosure of the chamber () of the cartridge (). To prevent the elastomer from infiltrating into the chamber () of the cartridge and/or its enclosure from breaking, cover-plates () performing mechanical protection and dielectric deflection cover the covers () of the chamber () and their braze () with the ceramic tube ().

Insulation of a switchgear device of vacuum cartridge type by insert moulding

The device according to the invention comprises an armature mechanically connected to an actuating rod of the contacts of the apparatus and movable in a support block between a rest position and an active position, at least one permanent magnet and at least one winding. The magnet(s) has(have) the function of holding the armature in the rest position whereas the winding(s) has(have) the function of generating, when an opening order occurs due for example to a voltage surge or other (or respectively a closing order), a magnetic field designed to counteract the force of the magnets so as to move the armature to the active position resulting in separation of the contacts (or respectively closing of the contacts). This device is characterized in that the above-mentioned armature is mounted movable in rotation between two stops arranged in the support, said stops respectively bounding the two above-mentioned positions.

Opening and/or closing control device, in particular for a switchgear apparatus such as a circuit breaker, and circuit breaker equipped with such a device
