An electric power circuit breaker with an energy storage device and an indicating device including an indicator lever with an indicator and an indicating cam of loaded and unloaded states of the loading mechanism. The indicating cam is mounted on the loading shaft in proximity to the loading cam, and includes a notch for receipt of the indicator lever when the mechanism is in the loaded state. The indicating cam includes a single ramp for progressively bringing the indicator lever into position up to the notch to guarantee latching of the opening latch maintained in a tripped position by the auxiliary release.
