Abstract

UN INTERRUPTOR MAGNETOTERMICO QUE TIENE UNA PROTECCION TERMICA QUE PUEDE CALIBRARSE MECANICAMENTE, CUYO CAJETIN (50) ESTA DOTADO DE UNA ABERTURA (25) PARA DETECTAR, POR MEDIO DE UN SENSOR (33) INTRODUCIDO EN LA ABERTURA (25), LA POSICION DE DESCANSO (CON RESPECTO AL CAJETIN) DEL EXTREMO LIBRE DE UN ELEMENTO BIMETALICO QUE ACTIVA LA PROTECCION TERMICA, ADAPTADO A UN SOPORTE VOLADIZO (9, 67) PARA PERMITIR DE ESTE MODO QUE EL SOPORTE (9, 67) PUEDA AJUSTARSE PARA HACER QUE EL EXTREMO LIBRE DEL ELEMENTO BIMETALICO (10) ADOPTE UNA POSICION DE DESCANSO PREDETERMINADA CON RESPECTO A LA CAJA (50).A MAGNETOTERMICO SWITCH THAT HAS A THERMAL PROTECTION THAT CAN BE MECHANICALLY CALIBRATED, WHOSE CASE (50) IS EQUIPPED WITH AN OPENING (25) TO DETECT, BY MEANS OF A SENSOR (33) INTRODUCED IN THE OPENING (25), WITH REGARD TO THE CASE) OF THE FREE END OF A BIMETALLIC ELEMENT THAT ACTIVATES THE THERMAL PROTECTION, ADAPTED TO A CANTILEVER SUPPORT (9, 67) TO ALLOW THIS SO THAT THE SUPPORT (9, 67) CAN BE ADJUSTED TO MAKE THE FREE END OF THE BIMETALLIC ELEMENT (10) ADOPT A REST POSITION DEFAULT WITH RESPECT TO THE BOX (50).
