CHNT #MotorProtector JD-8-2A-30A

#JD-8-2A-30A is a comprehensive motor protector of the #CHINT brand, mainly used for protecting three-phase AC asynchronous #motors against faults such as overload, #phaseloss, and overcurrent. The following is a detailed analysis based on the existing information:
I. Core Functions and Technical Parameters
1. **Protection Functions*www.transformerandswitchgear.com/721.html*
- **Overload Protection**: Monitor the motor current through the inverse time-delay characteristic (4-60 seconds). When the current exceeds the set value, the circuit will be automatically cut off.
- **Phase Loss Protection**: Detect the imbalance of three-phase current. When any phase is missing, the protection will be triggered within 2 seconds.
- **Overcurrent Protection**: Support rapid response to short-circuit faults (0.2 seconds).
- **Other Functions**: Some models support undervoltage, overvoltage, and leakage protection (specific models need to be confirmed).
