Abstract
An extractable circuit breaker is equipped with an operating lever which can take at least three positions: an inoperative position, an opening control position in which operating lever operates in conjunction with an opening latch of the circuit breaker, and a closing control position in which it operates in conjunction with a closing latch of the circuit breaker. When the circuit breaker is in the plugged-in position, the operating lever is inoperative. When the circuit breaker leaves its plugged-in position, the operating lever operates in conjunction with a countergear lever supported by the fixed frame accommodating the circuit breaker and performs opening of the poles of the circuit breaker. When the circuit breaker passes beyond its plugged-out position in the extraction direction, the operating lever moves from its inoperative position to its opening control position and then to its closing control position, causing opening followed by closing of the poles. In the extracted position, the circuit breaker is thus open and unloaded.
