A compensation bimetal having at least two bends configured to reverse the direction of the compensation bimetal to form “S” curves is disclosed. The first end of the compensation bimetal is coupled with a differential lever while the second end is coupled with a tripping pin, and the length of the multi-metallic strip is greater than the distance between the differential lever and the tripping pin. The compensation bimetal may be bimetallic, trimetallic strip, or tetra-metallic. The compensation bimetal with the described configuration compensates for a greater range of ambient temperature fluctuations while preserving sensitivity to thermal tripping due to over-current conditions.
