Abstract

An auxiliary contact accessory device for a magnetothermal circuit breaker, particularly of the bipolar type with phase and neutral poles, which is associated therewith, comprising an insulating casing which contains fixed contacts and a corresponding moving contact, connection terminals, and a kinematic mechanism, characterized in that the kinematic mechanism comprises: means for coupling to the circuit breaker; means for actuating the moving contact; means for the local visual indication of an open circuit breaker state; means for testing the correct operation of said fixed and moving contacts. <IMAGE>
