The 17AM-X heating wire protector is a protective device that provides triple protection of temperature, current, and time. It can accurately control the damage caused by motor stalling or excessive current to the motor. This product uses bimetallic materials with good conductivity to ensure that it can withstand the requirements of normal circuit currents. The combination of bimetallic sheets and electric heating wires has fast tripping ability, which can accurately control the tripping time and prevent motor burnout caused by high coil temperature.
