Abstract (en)
[origin: EP2650891A1] The device has an interlocking device arranged between a primary shaft (3) and a secondary shaft. The interlocking device prohibits earthing of two parts of an electrical circuit when an electrical protection apparatus is in a closed position. The interlocking device co-operates with a sensing device, a bolt (29), a bent part (17) and two portions (18, 19) of the bent part to prohibit earthing of the circuit when contacts of the protection apparatus are welded, where the sensing device, the bolt, the bent part and the portions are controlled by the secondary shaft.
