| Zusammenfassung: | A touchless magnetic-only coupled solenoid trip system for a miniature circuit breaker achieves magnetic tripping using a floating plunger assembly in a solenoid coil/housing to narrow a magnetic gap between plunger and trip assembly to cause the magnetic trip The floating plunger of the solenoid can also move out of the way if the bimetal bends to cause a thermal trip. |
