#CMT# #/CMT# The module (1) has two pairs of mobile contacts (6a, 6a`, 6b, 6b`) mounted in rotation around a rotation axis (A) and coupled by a rotation driving mechanism (7). The driving mechanism is arranged for inversing rotation direction of one pair with respect to the other pair so that in interlocked position current circulates from an upstream fixed contact (4a) to a downstream fixed contact (4b) in describing a crossed loop (B). #CMT#USE : #/CMT# Used in an electrical apparatus (claimed) e.g. interrupter, fuse interrupter, simple or overlay switch, circuit-breaker, and other disconnection, mono or polyphase electrical apparatus, that is utilized for distributing and controlling electrical energy of an installation. #CMT#ADVANTAGE : #/CMT# Construction of the module permits to obtain an increased disconnection speed, thus presenting a better electromagnetic behavior to reduce the formation of electrical arcs. The module is economic and presents simple design and a universal design so that the module can be used in different versions of electrical apparatus. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a disconnection module in an interlocked position. A : Rotation axis B : Crossed loop 1 : Disconnection module 4a : Upstream fixed contact 4b : Downstream fixed contact 6a, 6a`, 6b, 6b` : Mobile contacts 7 : Rotation driving mechanism. |
