Function and Usage
The JD-5 Motor Protector is suitable for AC motors with an AC rated insulation voltage below 690V, a rated operating current of 0.5A~400A, and a frequency of 50Hz, for long-term or intermittent operation, to provide overload and phase failure protection. The protector is generally used in conjunction with an AC contactor. It complies with the standards: GB/T 14048.4 and IEC 60947-4-1.
