Abstract
An overload release includes a bimetallic element, a tripping slide, a latch and an energy store. In an overload situation the bimetallic element actuates the tripping slide; as a result, the tripping slide actuates the latch, and as a result, the latch allows the movement of the energy store. The latch is provided with a latch area and the energy store is provided with a latching area, the two areas mechanically interacting in the latched state and the latch area being released from the latching area in the unlatched state, when there is an overload, to allow the movement of the energy store. Further, the latch area or the latching area includes a projection.
