ABSTRACT:
A thermal motor protector includes a first support for supporting a thermally responsive element and a second support for supporting a fixed contact. The first and second supports are mounted on and insulated from a header plate. The thermally responsive element is secured to the first support through a fixing strip and has a central shallow dish-shaped portion and carries a movable contact at its distal end. A calibration mechanism includes a male screw, a hole formed in the first support and elastically slender clamping portions clamping the screw when it is screwed into the hole. The diameter of the hole is smaller than the outer diameter of the screw. The stiffness of the fixing strip is determined so that variations in the ratio of the current bypassed into the calibration mechanism to the current flowing through the fixing strip and thermally responsive element can be substantially ignored.
