PCT No. PCT/DE88/00693 Sec. 371 Date May 24, 1990 Sec. 102(e) Date May 24, 1990 PCT Filed Nov. 4, 1988 PCT Pub. No. WO89/05036 PCT Pub. Date Jun. 1, 1989.A contact configuration (1) for low-voltage circuit-breakers has main and arcing contacts (6, 17; 10; 21) as well as arcing horns (22, 23) for transferring an arc into an arc quench chamber. Additional arc conducting pieces (30; 40) take over partial arcs that can occur on the main contacts (6; 17) when the contact configuration (1) is highly stressed, and carry them over to the corresponding arcing horn (22). The arc conducting pieces (30; 40) are designed more or less as angular, one-piece, stamped, flexural parts, whereby an arc conducting shank (36), which originates at a base shank (31) used for mounting is linked up at a sharp angle to the arcing horn (22).
