Abstract (en)
[origin: WO8802178A1] Circuit breaker with a number of movable contact members (20) and a corresponding number of fixed contact members (25, 26) where at least one of the contact members comprises a spring-loaded set of contact rolls (20) with several rolls (21, 22, 23, 24) arranged in such a way as to contact plane side surfaces of two contact bars (25, 26) between the rolls, said rolls being able to glide or roll on said surfaces during the closing and opening of the circuit breaker. In order to limit the necessary travel of the movable contact members between the closing and the opening it is suggested to arrange the set of contact rolls (20) and the co-operating contact bars (25, 26) so that they form a stepped engagement. Thus the physical dimensions of the circuit breaker are reduced compared to the prior art, even with circuit breakers with several poles and for heavy currents.
