Abstract
A removable calibrating unit comprises a body, a front panel and a part in the form of a reversible ramp. The reversible ramp comprises an end close to the front panel and an end away from the front panel. Extraction of the removable unit is achieved by means of a pin comprising an extraction lug. When the pin is subjected to rotational movement in one direction, the lug moves from the end close to the front panel to the end away from the front panel and results in extraction of the unit by applying thereon a force separating the unit from the circuit breaker.
