Abstract:
A circuit interrupter, comprising:a housing with a pocket for an auxiliary device means;operating mechanism means disposed within said housing for causing said circuit interrupter to attain a circuit interrupter status, said operating mechanism means having an operating mechanism means member which attains a predetermined position in said housing upon an occurrence of said circuit interrupter status, said operating mechanism means member being accessible from said pocket through an opening in said housing;separable contact means disposed within said housing in cooperation with said operating mechanism means for being opened by said operating mechanism means;auxiliary device means disposed in said pocket and having a reaction member for reacting to said occurrence of said circuit interrupter status;multi member lever means disposed in said auxiliary device means for interlinking said operating mechanism means member with said reaction member by way of said opening in said housing;said multi member lever means, comprising:a first member disposed in and rotationally supported in said pocket for being rotated through a predetermined first angle for actuating said reaction member;an axial hub member protruding from said first member;a second member disposed on said hub member and protruding into said opening for being rotated by said operating mechanism means member through a predetermined second angle during which said first member is rotated through said predetermined first angle for actuating said reaction member, said second angle being greater than said first angle; andspring means disposed upon said hub member and loaded between said first and second members for causing said first and second members to rotate in unison through said first angle, and allowing said second member to continue to rotate relative to said first member until said second member rotates through said second angle.
