Automatic Reset 17AM Thermal Protector 250V / 8A With Customized Lead Wire
Description
17AM is a thermally operated snap-action device which delivers the over heat protection with advanced structure, high contact capacity and long cycle life. The operating principle of the 17AM-D is both simple and effective. At the heart of the proctor is a bimetal snap–action disc. When the temperature of this disc reaches its pre-calibrated temperature it snaps open, resulting in an open circuit. This temperature is reached during a fault condition, caused by either an increase in ambient temperature, an increase in current flowing through the discs, or a combination of both. After the 17AM-D breaks the circuit, the system cools and the 17AM-D automatically resets, allowing power to be restored to the circuit.
