Abstract
A vacuum circuit-breaker wherein at least in one of the contacts at least one stud is used as a spacer, and is disposed between the mechanical connection portion and the circular plate of the contact body in such a manner as to avoid the collapse thereof during a closing operation of the vacuum circuit-breaker, and in the closed position the contacts can withstand very high compression forces, typically greater than 700 kg-force or 2 t-force.
