Abstract (en)
[origin: EP0619592A1] The two arc extinction chambers (84), (86) include a common end plate (102), of conducting material, arranged opposite fixed contacts (34), (36), and serving both as an element for shunting the moving contact (24) at the end of opening travel after switching of the arc onto the said end plate (102), and as an element for series electrical coupling of the two arc extinction chambers (84), (86). Application: Multi-pole circuit breaker with electrodynamic repulsion. <IMAGE>
