Abstract (en)
[origin: EP1207544A1] The circuit breaker contact zone (1) has a wedge-shaped annular gap (11a, 22a) between a contact surface (7,18) and an insulating covering (11,22) that opens in the radial direction from a contact edge (10,21) of the covering. The edge is dielectrically screened by an annular bead (8,19) protruding beyond the contact edge.
