Abstract
A magnetic trip device of a thermal magnetic circuit breaker and a thermal magnetic circuit breaker including such a magnetic trip device, and also a method for adjusting a magnetic field area of a magnetic trip device of a thermal magnetic circuit breaker, are disclosed. In at least one embodiment, the magnetic trip device includes at least an armature locator moveable arranged at a pin in order to adjust a magnetic field area, and an armature element fixed on a lower surface of the armature locator in order to interact with a yoke, arranged near a current conductive element for conducting electric energy. The armature locator includes an adjustment element arranged between a spring element and the yoke. The spring element surrounding at least a part of the pin is arranged between the armature element and the yoke.
