Abstract (en)

[origin: EP0206249A2] In a circuit breaker, which has fixed pressure reflector (3) and moving pressure reflector (5) respectively around its fixed contact point (1b) and moving contact point (4b) and an insulation barrier (6) for isolating a power source side space (P) and a load side space (L) thereby, at least one oblong protrusion is provided along the foot part (6c) of the insulation barrier (6); thereby undesirable flow of conductive powder from the contacts are prevented and insulation characteristic between the power source side space (P) and a load side space (L) is much improved.
