Abstract
A magnetic trip device of a thermal magnetic circuit breaker, a thermal magnetic circuit breaker that includes such a magnetic trip device, and a method for adjusting a magnetic field area of a magnetic trip device of a thermal magnetic circuit breaker, are disclosed. In an embodiment, the magnetic trip device includes at least an armature locator moveable arranged on 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. The armature locator includes a stabilizer element in order to increase a contact area between the pin and the armature locator and/or a recess in order to receive at least an upper end of a spring element in order to space the armature element and the yoke from each other at least partially.
