Panel D.O.L

 Panel Direct On-Line

Direct On-Line Control Panels are used for switching three-phase AC Motors/Submersible pumps up to 20 HP at 415V AC. A direct on line panel can be used if the high inrush current of the motor does not cause excessive voltage drop in the supply circuit. BOPARAI D.O.L Control Panels are configured from high quality material and give highly efficient performance. The Solenoid coils inside the contactors are machine-wounded using high-precision winding machines. Two types of Contactors are used in these panels. BOPARAI DC Contactors are of Air-Break type runs on 30 to 35 DC Voltages. These contactors provides silent and chatter-free operations even at low voltages and BOPARAI AC Contactors are also of Air-Break type runs on 240 to 415 AC Voltage. Parts of these contactors are easily accessible for cleaning, setting and replacement. . The contacts used in contactors are of high quality Silver Cadmium Oxide that provides long life and millions of trouble free operations.

Technical Specifications

These panels are specially designed for agricultural use, which are capable of restarting the motors automatically once the power in all the three phases resumes back.

These panels are specially designed for industries require manual operations.
