Motor Protector

EM500 series intelligent motor controller, is used for the contactor (AC 50Hz-60Hz, 690v, 820A) to provide all-round solutions for protection, measurement, display, diagnosis, electrical control, and communication of low-voltage motors, as it appears such obstacle as overheat, overload, current jam, under current, phase imbalance, ground fault, creep age, under voltage, over voltage etc.

The controller is based on the microprocessor and technology, and it has many advantages, including modular design, small volume, compact structure, convenient installation and so on. As compared with other traditional motor-protective devices, EM500 series, which can be directly, fixed in the low-voltage and motor control switchgears, and other above 1/4 -module types of switchgears, has much more reliability and more competitive price. 

In the fields of power, steel making, petrochemical, cement, gas industry and papermaking, EM500 series motor controller is widely used to provide reliable and efficient control for protection of low-voltage motors.
