  • the signaling device includes a so-called “any type of fault” signaling means, which is activated to signal the triggered state of the device upon the occurrence of an electrical fault, whether this fault is an overload or a short-circuit. circuit.
  • the signaling device also includes a so-called “second” signaling means, which can be activated to signal the triggered state of the device upon the occurrence of an electrical fault exclusively of the short-circuit type. This signaling device therefore allows the user to easily distinguish the type of fault which led to the device being triggered.
  • the second signaling means of this known device is moved by the striker of the magnetic trigger under the effect of the short circuit, the movement of the striker being transmitted to the signaling means via of a lever.
  • a magnetic trigger moves the striker with a relatively large effort when the magnetic fault occurs, capable of triggering the opening of the contacts and moving the signaling means, other types triggers do not develop such effort.
  • the constant need to miniaturize the triggers to miniaturize the protection device leads to obtaining triggers developing less effort.
  • certain triggers produce a low effort simply because of their operation.
