<p>The device has a set of thermal actuators (40), where each actuator is designed to react to a current overload in one of a set of phases by generating mechanical tripping commands (P1, P2). A transmission bar (31) is fitted on a support shaft, and a ratchet (30) is fitted on the support shaft. Another transmission bar (32) drives the ratchet from its latched position to its released position so as to change a state of an indicator. The former transmission bar and the latter transmission bar are disconnected from one another while pivoting around a pivoting axis (Y2, Y'2).</p> |
