Adjustable trip solenoid

An adjustable solenoid, comprising:

• an enclosure containing a winding through which a current is passed, said winding defining an area;
• a plunger being positioned at one end of said area, said plunger having an actuating member positioned to pass through an opening in said enclosure, said plunger being configured for movement between an actuating position and a non-actuating position;
• a mechanical biasing mechanism for providing a biasing force to said plunger, said mechanical biasing mechanism being secured to said plunger at one end and a support at the other;
• a stator being in a spaced relationship with respect to said plunger to define an air gap, said stator having a first threaded portion being engaged within a threaded opening of said enclosure, said first threaded portion and said threaded opening of said enclosure causing said stator to travel between a first position and a second position as a rotational force is applied to said stator, said first position being closer to said plunger than said second position;
• and
• a magnetic flux shifter coupled to said stator, said magnetic flux shifter being configured for movement within a range defined by a first position and a second position, said magnetic flux shifter shifting the magnetic flux of said solenoid as said magnetic flux shifter is moved from said first position to said second position, said second position causing said magnetic flux shifter to be positioned over said air gap.
