1. The temperature sensing surface of thermal cutout has to contact the heat source directly and tightly;
2. The contact surface must be flat and with good temperature conductivity. The fixing belt or fastener has to be reliable and no sharp edges, to avoid damaging the insulation of thermal cut out.
3. If surface of thermal cutout is electricity conductive, the insulation sleeving should contact the thermal cutout body as tightly as possible, to reach the best heat sensitivity.
