  • High inrush current circuit breaker
    Patent number: 4504807
    Abstract: A magnetic circuit breaker has a U-shaped magnetizable plate between the solenoid coil and the plastic spool flange located below the pole piece that is engaged by the armature to trip the breaker. This U-shaped disc diverts some of the instantaneous flux created by an inrush current spike away from the pole piece to prevent premature or "instantaneous" tripping of the breaker until a predetermined multiple of rated current is exceeded. In the preferred embodiment this disc is provided in a slot formed in the plastic spool flange itself.
