Product Introduction

It ensures reliable protection for switching electrical contacts when the motor's main circuit experiences abnormal operating conditions such as phase failure, overload, and stalling.

Product structure and performance characteristics

Application and Service Range: JD-6A Motor Comprehensive Protector, suitable for AC 50 /60Hz,voltage 220V or 380V power supply circuit and AC contact switch circuit composed of motor control circuit. The protection conform with the requiements in GB/T14048.4

Normal work condition: The altitude is not more than 20oo meters, the ambient temperature is not higher than + 40℃ and not lower than-5℃, rated control power supply voltage range of 85 %-110 % rated voltage, in the medium without serious vibration and explosion risk, and the medium is not enough to corrode the metal and damage the insulation of the gas and dust, in the rain and snow invasion of the place.
