Electrical switching equipment, has pinning and release mechanism provided such that rotation of levers permits one roller to provoke displacement of circuit-breaker and displacement of another roller to penetrate it into slot

摘要

The equipment has a pinning and release mechanism provided such that rotation of each lever permits one of the rollers (38a, 38b) penetrated inside one of the slots (44) to provoke a displacement of a circuit-breaker (20) in a pining and releasing direction. The mechanism provokes a displacement of another roller leading it to penetrate in the slot situated in a manner consecutive with respect to one of the slots.
