Abstract:
A single- or multi-pole power circuit-breaker, comprises main contacts, overload- and/or short-circuit current-actuated tripping means, an actuating mechanism for the main contacts, an arc chute and a pressure trip unit having a return element and an actuating element responsive to an overpressure in the arc chute. The tripping of the power circuit-breaker by a trip mechanism is executable both by the tripping means and the pressure trip unit. The pressure trip unit is arranged immediately adjacently to both the arc chute and a main busbar. A tripping lug mechanically engages with the trip mechanism such that an overpressure in the arc chute is transmitted virtually instantaneously to the pressure chamber. The actuating element is configured to switch over directly from a home position to a tripping position, against the force of the return element, in a case of overshoot of a pressure threshold value set by the return element.

Claim (Index 1):
A single- or multi-pole power circuit-breaker, comprising, for each pole:\n main contacts; overload- and/or short-circuit current-actuated tripping means; an actuating mechanism configured to open and close the main contacts; an arc chute; and a pressure trip unit having a return element and an actuating element responsive to an overpressure in the arc chute, wherein the tripping of the power circuit-breaker by a trip mechanism is executable both by the tripping means and by the pressure trip unit, wherein the pressure trip unit is arranged immediately adjacently to both the arc chute and to a main busbar which is routed to the respective main contacts, and is arranged within a closed pressure chamber which is connected to the arc chute, wherein at least one tripping lug which projects from the actuating element is configured to mechanically engage with the trip mechanism such that an overpressure in the arc chute associated with the generation of an arc between the main contacts is transmitted virtually instantaneously to the pressure chamber, where the overpressure acts on the actuating element of the pressure trip unit, and wherein the actuating element is configured to switch over directly from a home position to a tripping position, against the force of the return element, in a case of overshoot of a pressure threshold value which is set by the return element.
