Abstract (en)
[origin: EP0655759A2] Electrical Switchgear having a pair of main electrodes in contact in a first ON position, an arcing electrode electrically connected to and rigidly connected to one of the main electrodes and a resilient contact element electrically connected to and resiliently mounted with respect to the other main electrode. In operation the main electrodes move relative to one another from the first ON position through a second intermediate position to a third OFF position where, in the intermediate position the resilient contact element is in contact with the arcing electrode and in the OFF position the first and arcing electrodes are out of contact with the second electrode and resilient contact element. The switchgear being arranged such that the main electrodes can be moved from the third OFF position to the first ON position without the resilient contact element contacting the arcing electrode. <IMAGE>
