The advantage is
1, the volume is small, easy to achieve interchange with thermal relays.
2. There is no thermal relay which is prone to thermal fatigue and the technical parameters are difficult to recover the initial state. The protection parameters are stable and the repeatability is good.
3, with a variety of protection features and long life and other advantages. Widely used in petroleum, steel, metallurgy, textile, chemical, cement, mining and other industries.
Motor protector (electronic thermal relay) available
ZLDB motor protector (electronic thermal relay) is based on the principle of metal resistance voltage effect to realize various protections of the motor. It is different from the principle of metal resistance thermal effect of thermal relay, and is also different from the core-type motor protector (electronic thermal relay) current transformer. Principle of magnetic effect.
