This series of products is suitable for AC 50HZ(or 60HZ), voltage is 380V, power from 18.5-315KW three-phase squir-cage induction motor for self-coupling reduced pressure starting, and can accelerate the motor to the rated speed and stop the motor, the motor has overload, short circuit and other protection. This series of products are specially designed for the factory submersible pump, adding the motor stator over temperature protection and pump oil chamber leakage protection, and make the corresponding display of various faults.
The starter works reliably under the following conditions:
▲ The highest air temperature around is not more than +40 degrees, and the lowest temperature is not less than -5 degrees.
▲ The average value of 24h ambient air temperature does not exceed +35 degrees.
▲ The altitude of the installation site does not exceed 2000m.
▲ The monthly average maximum humidity of the air is not greater than 90% (the average temperature is 25 degrees).
▲ In conductive pollution or due to expected condensation dry non-conductive pollution into conductive environment (pollution level 3).
The control cabinet is suitable for the following working system:
▲ Long-term work system
▲ Eight-hour work system
▲ Repeated short-time working system: rated operating frequency of 12 times /h.
