Abstract

a presente invenção refere-se a uma unidade de desarme de um conjunto de comutação, em que o conjunto de comutação tem pelo menos um polo que tem um interruptor. a unidade de desarme tem um primeiro eixo acoplado com o interruptor para abertura e fechamento do interruptor. uma primeira alavanca está presa no primeiro eixo para girá-lo. a unidade de desarme também tem um mecanismo para automaticamente desarmar o conjunto de comutação, e um mecanismo para manualmente desarmar o conjunto de comutação. o mecanismo de desarme manual tem um engate para travar uma pega do mecanismo para prender o primeiro eixo em uma posição predeterminada. além disso, a unidade de desarme tem um mecanismo para impedir a rotação do primeiro eixo na posição predeterminada. o mecanismo compreende uma terceira alavanca intertravada com uma segunda alavanca do mecanismo de desarme manual, em que uma posição intertravada da terceira alavanca impede a rotação do primeiro eixo.The present invention relates to a trip unit of a switch assembly, wherein the switch assembly has at least one pole having a switch. The trip unit has a first shaft coupled with the switch for opening and closing the switch. A first lever is attached to the first shaft to rotate it. The trip unit also has a mechanism for automatically disarming the switch assembly, and a mechanism for manually disarming the switch assembly. The manual disarming mechanism has a latch for locking a handle of the mechanism for securing the first axis in a predetermined position. furthermore, the trip unit has a mechanism for preventing rotation of the first axis at the predetermined position. the mechanism comprises a third lever interlocked with a second lever of the manual disarming mechanism, wherein an interlocked position of the third lever prevents rotation of the first axis.
