A disconnector having a stack of modular contact boxes surmounted by a snap-action switch box, each modular contact box including a rotary contact and two fixed contacts which are accessible from the outside. The switch box further includes a driven indexing element which is rotatably associated with a spindle loading support and at least one spring connected between the two in order to load them elastically with respect to each other following a mutual rotation about the central axis. The disconnector has a single actuation rod which passes through all the modular contact boxes coaxially to the central axis and is fixed in rotation to all the rotary contacts.
A disconnector (1) that comprises at least two modular contact boxes (2), each one comprising a box-like body (3) coupled to a contiguous box- like body (3) of a contiguous modular contact box (2); each box-like body (3) defines a seat (40) that accommodates a moving contact (4) and two peripheral seats (50), each of which accommodates a corresponding fixed contact (5) that can be accessed from outside the modular contact box (2); the at least two box-like bodies (3) comprise at least one first box-like body (3a), in which at least the outward-facing surface has a first finish, and at least one second box-like body (3b), in which at least the outward-facing surface has a second finish, the contacts of the first box-like body or bodies (3a) having one polarity and the fixed contacts of the second box-like body or bodies (3b) having an opposite polarity.
A disconnector for photovoltaic applications having at least two modular contact boxes, each contact box having a box-like body coupled to a contiguous box-like body of a contiguous modular contact box. The box-like body forms a central seat that accommodates a rotatable contact and two peripheral seats, each of which accommodates a connection portion of a corresponding fixed contact that can be accessed from the outside of the modular contact box. The rotatable contact is able to rotate about the axis of the central seat with respect to the box-like body in order to engage the fixed contacts arranged with their connection portion in the peripheral seats or to disengage from the fixed contacts.
