Abstract: PROBLEM TO BE SOLVED: To improve operation dissymmetry of the other pole to the center pole of an operating mechanism of a multi-pole circuit breaker.SOLUTION: A switchgear device 600 has a main unit Bp supporting an operating mechanism 8, and at least a first auxiliary unit Ba1. Each of these units has a rotation bar coupled to a mobile contact bridge guided in the case of rotation around a rotation axis Z. Two stationary contacts collaborate with the mobile contact bridge. The operating mechanism 8 controls at least one driving rod 30. The angular movement of the at least one driving rod 30 causes the angular movement of the mobile contact bridges between an opening position and a closing position. Compensation means comprises a stop 60. The stop 60 is pressed at the closing position. By this pressing, the driving rod 30 restricts the movement of the rod at a level of the first auxiliary unit Ba1, and applies a rotation torque to the rod to hold it parallel to the axis Z.

Abstract: A pressure sensitive trip mechanism for actuating a circuit breaker operating mechanism to trip a circuit breaker includes a trip lever and a trip bar. The trip lever is rotatable about a first pivot. The trip bar is positioned proximate the trip lever. The trip bar is arranged to rotate about a second pivot in response to a predetermined level of pressurized gas created by separation of the pair of electrical contacts, thereby urging the trip lever to unlatch the circuit breaker operating mechanism. The pressure sensitive trip mechanism provides for very fast tripping of the circuit breaker in the event of a short circuit condition or an overcurrent fault condition within any one on the circuit breaker poles. In a multi-pole circuit breaker, the present invention provides for protection against single-phasing.
