A device for transferring motion from a manual lever to a reset lever of a pressure trip mechanism in a molded case circuit breaker. The pressure trip mechanism is activated when hot gasses are released during an arc event and the resultant increase in pressure forces a piston in the mechanism to expand and thereby activate the breaker. In some interruption events, hot gasses, and occasionally fragments of molten metal, are responsible for marring the plastic piston surface of the pressure trip mechanism and prevent the mechanism from returning to its pre-interruption position even when it is biased to the pre-interruption position with a spring. A configuration disclosed herein provides for linking the motion of the hand-driven manual lever used to reset the breaker to the reset lever connected to the pressure trip mechanism in order to force the pressure trip mechanism to return to its pre-interruption position.
