JD-5 Electromotor protective relay is targeted three-phase motor is running due to broken phase (lack of phase), over-current devices such as failures caused by burning of electric motor designed for integrated protection device, protection devices used by the U.S. companies to import LM chip, designed a novel electronic products, there are very good anti-time characteristics, with run-off phase, the transition fault indicator. The product is fully functional, the provincial head intuitive, troubleshooting quick, reliable performance, low cost, easy installation. The product is used to protect the motor with a higher value.
