Electronic Relays

What is the definition of electrical overload relays? These products are a microprocessor-controlled device that protects three-phase and single-phase motors from the exorbitant temperature rise that is caused by overload and phase failure. Internal current transformers monitor the actual motor current in each phase in real time. A trip happens when the pre-defined operating value is achieved. After the electricity is restored, the relay returns to its previous position. In the case of an overload or a phase breakdown, an electronic overload relay protects motors in a dependable and timely manner. This product is self-powered, therefore, no additional external power is required.
