Abstract

The device has an expulsion channel (6) formed in the housing and associated with the breaker contacts (20), a lever (10) that interacts with the trip element (2) and a build-up surface (14) formed on the lever and associated with the expulsion channel for deflecting the lever to actuate the trip element as a result of a pressure step in the expulsion channel.
