Abstract
A temperature responsive device comprises a bimetal element (12) flexible on temperature and current overload conditions to engage a trip latch (14) to open the circuit. The bimetal element (12) is pivotally mounted between knife edges (22) provided on a mounting member (20), whilst one end portion of the bimetal element is connected to an adjustment means (24), by which said end portion may be moved, pivotally to move the bimetal element about its pivotal mounting.
