A overload protector is an electrical device which we use for compressors protection, whenever the compressor temperature high form his range the compressor overload cut off the electric supply form compressor motor that’s why we called him thermal overload.
The connection of overload with compressor in series and inside the overload we connect a heating resistance and with heating resistance we connect a bimetallic strip metals. The heating resistance and bimetallic strip metals both make a overload relay.
