Motor integrated protector ANY-JD8
ANY-JD7, ANY-JD8, ANY-JD9 series motor protector is suitable for AC 50HZ, voltage 24V~380V power supply circuit, and AC contactor and other switching devices to form the motor control circuit.
When the main circuit of the motor is out of phase, overload, stall, three-phase unbalance, etc., the protector can break the contacts of the switchgear in time, disconnect the three-phase power of the motor, and quickly and reliably protect the motor.
The protector adopts core-through current sampling detection technology, thyristor output, simple structure, convenient use, reliable operation, and has the advantages of no power consumption, long life, no arc during operation, etc., and is currently an ideal replacement for thermal relay in China. Motor protector.
The protector complies with the requirements of EN60947-1, EN60947-5-1, EN60204-1 and GB14048.4.

The main technical parameters
1. Phase failure protection: When any phase of the three-phase power supply of the motor is out of phase or the internal phase of the motor is out of phase, the protection action lag time ≦1S.
2. Three-phase unbalance protection: When the operating current of any two phases of the three-phase power supply of the motor differs by more than (50±10)%, the protection action lag time ≦1S.
3. Overload protection: When the working current of the motor reaches 1.2 times to 5 times of the rated value, the action lag time of the protector is 80S~10S (inverse time characteristic).
4. Output interface reset mode: control loop power-off reset, reset time (60+10)S
5. Working methods: Uninterrupted work system.
