A blade assembly for use in a circuit breaker, the blade assembly comprising a plurality of blades, including one or more pairs of adjacent side-by-side blades having coplanar contact surfaces and coplanar bearing surfaces, at least one set of blade springs, each having one end in operative contact with the bearing surface of each of a pair of adjacent side-by-side blades, the at least one set of blade springs comprising at least one compression spring.

Current carrying assembly for a circuit breaker

An electrical circuit breaker pole comprises a stationary contact means, a movable contact means, and an arc extinguishing chamber comprising two side flanges, separators, a front opening situated near to the contact zone of the stationary contact means, a lower arcing horn, an upper arcing horn and a pair of lateral dielectric shields laterally limiting the front opening of the chamber. Each lateral dielectric shield is arranged in such a way as to be interposed laterally between the separators and the movable contact means in the open position. The pair of lateral dielectric shields is arranged in such a way that the width of the opening of the chamber is appreciably smaller near to the upper arcing horn than pear to the lower arcing horn.
