Adjustable trip solenoid
An adjustable solenoid having an enclosure containing a winding through which a current is passed. The winding defines an area and a plunger is positioned at one end of the area with a mechanical biasing mechanism for providing a biasing force to the plunger, the mechanical biasing mechanism is secured to the plunger at one end and a support at the other end. A stator having a first threaded portion engaged within a threaded opening of the enclosure causes the stator to travel between a first position and a second position as a rotational force is applied to the stator. The first position is closer to the plunger than the second position, and the stator is in a facially spaced relationship with respect to the plunger and the stator has a second threaded portion for engaging a threaded portion of the support, the second threaded portion of the stator causes the support to travel between a first position and a second position, the second position of the support provides the mechanical biasing mechanism with a greater biasing force than the first position.
