Abstract

The test circuit (54) of a circuit-breaker with differential trip unit includes a first conducting strand (72) shaped as a test contact for a test switch, and as an elastic return element for the test button (56), and a second conducting strand (74) configured as a self-cutting contact for a protective switch (62) cooperating with a transmission component (64) of the mechanism (50). The two strands (72, 74) form part of a double spring (66) having two helical windings (68, 70) fitted coaxially on a common spindle (71) and connected to one another by an intermediate link (76) bearing on a support (78) of the casing (12).
