ST10 Thermal protector
ST10 high-current thermal protector is a high-current protector with overcurrent, overheating double protection function, built-in heating plate and bimetal disc to form a series circuit. The overload current when the motor is blocked will make the heating wire heat up rapidly, which will heat the bimetal disc and accelerate the heating speed of it, so that the bimetal disc can reach the rated operating temperature faster and bounce open, cutting off the circuit.
