Resetting RCD mechanism by the handle

An electrical protection device, comprising:

• a casing;
• a first conduction path, which comprises a first movable contact housed in the casing and movable between a conduction position and an isolation position;
• a switching mechanism, which is housed in the casing and which is configured to switch between:
• a set configuration, in which the switching mechanism places the movable contact in the conduction position;
• and
• a tripped configuration, in which the switching mechanism places the movable contact in the isolation position;
• a first tripping device, which is housed in the casing and which is configured to trip switching of the switching mechanism from the set configuration to the tripped configuration when the first tripping device is initiated by a first type of electrical fault;
• a switching lever;
• rotatable about a lever axis;
• operable by a user between an open position, for placing the switching mechanism in the tripped configuration, and a closed position, for placing the switching mechanism in the set configuration;
• and
• operable by the switching mechanism from its closed position to its open position, when the switching mechanism is switched to the tripped configuration under the effect of the first tripping device;
• a slide, which comprises a locking relief and which is movable relative to the casing, between a set position and a disengaged position;
• a slide spring, which applies an actuating force to the slide, tending to move the slide from the set position to the disengaged position;
• a latch, which comprises a blocking relief configured to block the slide in the set position, the latch being movable between a holding position, in which the latch holds the slide in the set position by means of the blocking relief, which engages with the locking relief when the slide is in the set position, and an unlocked position, in which the blocking relief and the locking relief are offset relative to each other and the latch allows the slide to be moved from its set position to its disengaged position, the first tripping device being configured to move the latch from the holding position to the unlocked position when the first tripping device is initiated;
• wherein
• the electrical protection device further comprises a resetting hook, kinematically linked to the switching lever, such that it moves with the switching lever when the switching lever rotates about the lever axis between its open position and its closed position;
• the slide supports a slide hook;
• when the slide is in the disengaged position:
• the resetting hook and the slide hook face each other and are ready to be engaged by rotating the switching lever between its open position and its closed position;
• the latch is held in the unlocked position by the slide;
• when the slide is in the set position, the slide hook and the resetting hook are spaced apart from each other;
• and
• the transition of the switching lever from its open position to its closed position causes the slide hook and the resetting hook to engage and the switching lever to move the slide until the electrical protection device is reset, with the slide transitioning from its disengaged position to its set position and the switching mechanism switching to the set configuration.
