Abstract

The quick action circuit breaker consists of a frame, two contact pieces and two actuators. The second actuator is suitable to operate the second contact piece relative to the frame as a function of an externally applied signal. The first actuator can switching the contact pieces automatically to positions where they are separated as soon as the value of the current reaches a threshold value. The frame is formed by a plate (1) with two cams (2, 3). They are formed as an integrated unit from insulated material. There are parallel metallic shafts (4, 5, 6, 7, 52). A curved conductor (9) a connecting strip (10) and a very flexbiel conductor (11) are connected to the cam. The first actuator is semi-pneumatic, where the first contact is actuated by a piston. The cylinder is fitted with a valve.
