Abstract: A switchgear device comprising a main unit supporting an operating mechanism and at least a first auxiliary unit. The units respectively comprise a rotary bar coupled with a mobile contact bridge guided in rotation around an axis of rotation. Two stationary contacts collaborate with said mobile contact bridge. The operating mechanism commands at least one drive rod, angular movement of which results in that of the mobile contact bridges between an open position and a closed position. Compensation means comprise a stop against which the drive rod presses in the closed position so as to limit movement of said rod at the level of the first unit, and to apply a rotational torque to said rod to keep it parallel to the axis.

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.
