Abstract
Within an envelope, the medium or high voltage circuit breaker includes first and second main contacts that are movable relative to each other along a common axis, first and second arcing contacts that are movable along the common axis, the first arcing contact being secured to the first main contact, and a device for transmitting displacement to the second arcing contact in a direction opposite to the displacement of the first main contact and the first arcing contact. The device includes two wheels mounted in fixed positions in the circuit breaker and in alignment on the common axis, and a transmission belt looped around the two wheels, thereby enabling the second arcing contact to be displaced relative to the first contacts by means that occupy little space.
