Dragon UL-E20 series motor protectors are the latest products developed according to the development trend of low-voltage electrical appliances in the world. UL-E20 series protectors have symmetry faults (such as overload, overcurrent, and stall) and asymmetrical faults (such as various phase failures, current imbalances, phase-to-phase short circuits, and inter-turn short circuits), and phase sequence and overvoltage Undervoltage protection. The protector has the characteristics of simple structure, complete functions, high precision, reliable operation, convenient use and small size, and is an ideal replacement for the thermal relay, and is particularly suitable for occasions where the working environment is harsh and the quality of the power grid is poor.
