Electric current breaking apparatus, in particular a coupling breaker

摘要

#CMT# #/CMT# The apparatus has a movable contact carrier shaft (8) whose rotation axis (33) is brought closer to a rotation axis (29) of a rotation compensating thermal switch (27). The shaft comprises a part (34) that cooperates with another part (35), where the latter part is rotationally fixed to the switch. The two parts are arranged relative to each other such that the former part rotates the latter part and the switch in a direction opposite to a releasing direction of a mechanism until obtaining re-attachment of the switch and an active thermal switch (26) relative to each other. #CMT#USE : #/CMT# Electric current breaking apparatus i.e. coupling breaker, for arrangement between a meter and an electric switchboard (all claimed) in an electrical supply network. #CMT#ADVANTAGE : #/CMT# The two parts are arranged relative to each other such that the one of the parts rotates the other part and the rotation compensating thermal switch in the direction opposite to the releasing direction of the mechanism until obtaining re-attachment of the switch and the active thermal switch relative to each other, so that requirement of additional rods or adapters is avoided, thus reducing number of parts in the apparatus, and hence assembling the apparatus in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an electric current breaking apparatus with two elements in a closed position of a non-triggered mechanism. 8 : Movable contact carrier shaft 26 : Active thermal switch 27 : Rotation compensating thermal switch 29 : Rotation axis of rotation compensating thermal switch 33 : Rotation axis of carrier shaft 34, 35 : Parts.
