Description
This product is used in conjunction with PTC thermistor temperature control sensors. Shockproof, moisture-proof, high sensitivity, and reliable operation. Used for overtemperature protection of motors or other devices. The PTC thermistor temperature control sensor is connected to the signal input terminal of the protector. When the temperature of the temperature measurement point rises, the sensor resistance value increases. When the resistance value reaches the action threshold of the protector, protection is implemented.
Technical parameters:
Insulation strength:AC2500V/50Hz,1min
Power consumption:≤1W
Contact capacity:6A
Working environment: temperature 0 ℃~50 ℃; Temperature<90RH%

Installation precautions
1) Firstly, confirm whether the power voltage of the protector meets the requirements;
2) Fix the protector inside the electric control cabinet and connect it to the motor control circuit as shown in the wiring diagram;
3) The control and protection circuit should be equipped with a 0.5A fuse to ensure the safety of the control circuit;
4) After installation and power transmission, the protector relay should switch from normally open to normally closed, and the green indicator light should light up, indicating that the protector status is normal.
