369-H1-R-M-F-E-H-E motor protector (electronic thermal relay) is based on the principle of metal resistance voltage effect to achieve a variety of motor protection, which is different from the principle of metal resistance thermal effect of thermal relay, and is also different from the principle of magnetic effect of current transformer of through-core motor protector (electronic thermal relay). Its advantages are 1, small volume, easy to realize and thermal relay interchange. 2, there is no thermal relay prone to thermal fatigue and technical parameters are difficult to restore the initial state, stable protection parameters, good repeatability. 3, with a variety of protection functions and long life and other advantages. Widely used in petroleum, iron and steel, metallurgy, textile, chemical, cement, mining and other industries.
