Abstract: An electrical switching apparatus (2;50) includes separable contacts (10), an operating mechanism (16) structured to open and close the separable contacts, and a trip mechanism (14) cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a trip latch (4), and an arc chamber (18) operatively associated with the separable contacts. The arc chamber includes a plurality of arc plates (20) and a barrier (22) disposed between the arc plates and the trip latch. The barrier has an opening (12;58) therein. A trip member (8) is disposed in or about the opening of the barrier of the arc chamber. During interruption of current flowing through the separable contacts, pressure arising from an arc (11) in the arc chamber pushes the trip member away from the barrier of the arc chamber to engage the trip latch and cause the trip mechanism to trip open the separable contacts.

Abstract: 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.
