Abstract

The balanced armature pivots on one pole piece and has a small contact surface that cooperates with the other pole piece. Movement of the armature is coupled to the tripping catch that operates the circuit breaker by a lever connected by an axle to the armature. One spring biases the armature open and closed when the latter is respectively closed and open. Another sprig biases the armature open at all times. The lever arms through which the springs and the magnetic attractive force act on the armature are so chosen that the magnetic tripper is highly sensitive and vibration proof.
