Aug 24, 2017 · As this bimetallic strip heats up, one metal will expand faster than the other and cause the assembly to curve. When it gets hot enough the curvature will be enough for the contacts in the overload to become separated. Since the overload has a contact wired into the control circuit of the contactor, this effectively breaks the circuit and de ... A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated. The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature.A variety of thermostats use bimetallic strips. Because of the difference in coefficients of expansion between the two metals, the strip changes its curvature as the temperature changes. Most often, the strip closes or opens an electrical contact to turn a heater or cooler on or off, depending on the application.The bimetallic strip gets heated up by the current directly or indirectly and when the current flow exceeds the set value, it bends.
