Abstract
Il gruppo è associabile ad un interruttore sotto carico (IS) che può essere comandato in due interventi a due valori di extracorrente tramite una articolazione (10, 16) di doppio comando atta ad agire sull'organo (C) di comando di detto interruttore sotto carico (IS) da parte dell'uno o dell'altro di due organi di scatto (1A, 20) controllati l'uno dalla valvola fusibile (VF) e l'altro dalla bobina elettromagnetica (22); un temporizzatore (101, 120) permette l'apertura dell'interruttore sotto carico (IS) dopo che è trascorso il tempo di fusione della valvola fusibile (VF).(FIG. 2)The group can be associated with an on-load circuit-breaker (IS) which can be controlled in two interventions at two overcurrent values by means of a double-control articulation (10, 16) adapted to act on the control organ (C) of said circuit-breaker under load (IS) by one or the other of two tripping elements (1A, 20) controlled one by the fuse valve (VF) and the other by the electromagnetic coil (22); a timer (101, 120) allows the circuit-breaker to open under load (IS) after the melting time of the fuse valve (VF) has elapsed. (FIG. 2)
