This invention belongs to the field of thermal protector testing technology, specifically a thermal protector testing device, comprising: a housing with an operating cavity inside; a slide rail symmetrically arranged on the inner wall of the operating cavity; a movable plate with its bottom slidably connected to the top of the slide rail; and a testing mechanism symmetrically arranged on the top of the movable plate. This invention, through the installation mechanism, ensures that the wires of the thermal protector element are attached to and connected to the herringbone tube, maintaining inward transmission and contact with the drive seat to form a series circuit. The testing mechanism heats the thermal protector element until it breaks the circuit, causing the bulb to lose power. The heating temperature at this point is recorded. Individual temperature testing is performed on each thermal protector element, avoiding the inaccurate measurement of the power-off temperature of each thermal protector caused by overall heating. This allows for convenient and quick installation of the thermal protector element, saving workers' disassembly and assembly time and improving testing efficiency.
