Abstract

Differential circuit-breaker formed by the modular assembling of a circuit-breaker unit (11) with separable contacts, and with control mechanism (18) with handle, and of a differential trigger unit (20) having a triggering relay (26), a first mechanical link (27) for triggering the mechanism (18), a second mechanical link (45) for automatic resetting of the relay (26), a test circuit (28) with test button (44), and a control for remote opening by remotely-controlled contact (46). One of the faces of the casing of the trigger unit (20) engaging with the circuit-breaker unit (11) contains openings for transverse passage of the first and second mechanical links (27, 45). The other opposite face of the casing serves alternately as support, either to a detector unit (150) enclosing a totalising transformer (21), or to an auxiliary unit (202) containing an electronic circuit (204) driven by triggering and supply signals coming from the separate detector unit (150). <IMAGE>
